+# Linux Support #
+
+## Overview ##
+
+Linux support for Garmin GPS devices, especially those which monitor non-location data such as heartrate, is very poor. The situation is further confused by a plethora of conflicting, poorly documented file formats and outdated instructions. The following covers my process for downloading information from my Garmin Edge 305 bicycling GPS to a Linux workstation, including automatic file conversion to the TCX format since it is both supported by GoldenCheetah cycling software and, as an easily manipulated XML based format, should be easily convertable into other formats for many years to come.
+
+## Instructions ##
+
+First, disable the `garmin_gps` kernel module. On Debian wheezy this is accomplished by writing the following line to `/etc/modprobe.d/garmin-gps-blacklist.conf`
+
+    blacklist garmin_gps
+
+Download, build and install the `garmintools` package. The tarball contains a README that explains this process. This provides the `garmin_save_runs` program which will download data from your Garmin GPS and save it in the Garmin binary GMN format. It also includes the `garmin_dump` program which will convert a GMN file to an XML-life format. Note that you will need to be root, or set appropriate permissions for your user to have USB access. A sample run is shown below.
+
+    Extracting data from Garmin EDGE305 Software Version 3.20
+    Files will be saved in '/mnt/documents/Bicycling/logged_data'
+    Wrote:   /mnt/documents/Bicycling/logged_data/2014/07/20140724T230419.gmn
+    Wrote:   /mnt/documents/Bicycling/logged_data/2014/07/20140729T152915.gmn
+
+Once you have obtained a GMN file, download the garmin-dev-master zip file. The `gmn2tcx` program accepts the GMN file as its sole argument and outputs the TCX file to stdout, as well as status messages (including success messages) to stderr. You will need to have `garmin_dump` from the garmintools package in your PATH environment variable. As an example, the following will create a new TCX file from an existing GMN file while still displaying status messages on the terminal.
+
+    ataylor:~$ /usr/bin/gmn2tcx ./sample.gmn > ./sample.tcx
+    - validates
+
+To simplify the process, I created a small wrapper script that wraps these tools and performs the following operations.
+
+* Extract new tracks from GPS as GMN for archiving
+* Create TCX copy of new tracks for use performance tracking software
+* Save session log for troubleshooting
+
+The script uses python and can be configured by editing the configuration values located in the first few lines. After each cycling session you will only need to connect your Garmin device, execute the script and then launch the cycling software of your choice. 
+

+# Overview #
+
+As a professor of Japanese, my wife requires her students to use [genkouyoushi paper](http://en.wikipedia.org/wiki/Genk%C5%8D_y%C5%8Dshi genkouyoushi paper) on most written assignments. Although this can be purchased in Japanese bookstores (or online) and can be found freely on many websites as a PDF, the lack of control over size, spacing and color frustrated her. The following source code generates genkouyoushi paper via LaTeX and is easily customizable to match any layout the user may desire.

+NED - Architecture Manual
+=========================
+
+Instruction Word Formats
+------------------------
+
+All instruction words in NED are 32-bits long and fall into one of three
+possible formats.
+
+    +---------+-----+-----+--------+--------+--------+--------+--------+
+    |  Format |  31 |  30 | 29..24 | 23..18 | 17..12 |  11..6 |  5..0  |
+    +---------+-----+-----+--------+--------+--------+--------+--------+
+    |    A    |  1  |                  31-bit Immediate                |
+    +---------+-----+-----+--------------------------------------------+
+    |    B    |  0  |  1  |               Unassigned                   |
+    +---------+-----+-----+--------+--------+--------+--------+--------+
+    |    C    |  0  |  0  | Syl. 1 | Syl. 2 | Syl. 3 | Syl. 4 | Syl. 5 |
+    +---------+-----+-----+--------+--------+--------+--------+--------+
+
+Format A contains a 31-bit field which is placed on the stack after shifting
+left one position and padding with a zero. For example, the instruction
+
+    11000000 01000000 01000000 01000000
+
+will place the value
+
+    10000000 10000000 10000000 10000000 
+
+on the TOS.
+
+Format B is reserved for future instructions.
+
+Format C packs five syllables per instruction word, executed in order from 1 to 5.
+Syllables are defined as follows.
+
+|  Bits  |  Name  |  Description                                               |
+| ------ | ------ | ---------------------------------------------------------- |
+| 1xxxxx | IM_x   | Push a 5-bit immediate to TOS.                             |
+| 011xxx | LDSP+x | Copy the value stored at TOS+x and push to TOS.            |
+| 010xxx | STSP+x | Pop from TOS and overwrite value at TOS+x.                 |
+| 001000 | AND    | Logical AND of TOS and NOS, pushed to TOS.                 |
+| 001001 | OR     | Logical OR of TOS and NOS, pushed to TOS.                  |
+| 001010 | NOT    | Logical NOT of TOS, pushed to TOS.                         |
+| 001011 | XOR    | Logical XOR of TOS and NOS, pushed to TOS.                 |
+| 001100 | ADD    | Signed, twos-complement addition. TOS <- TOS + NOS         |
+| 001101 | SWAP   | Swap TOS and NOS.                                          |
+| 001110 | JMP    | Pop TOS and set PC to popped value.                        |
+| 001111 | MVSTCK | Pop the TOS and context switch to that state ID.           |
+| 000100 | SHIFT  | Pop TOS & NOS. Shift NOS by TOS bits to the left/right.    |
+| 000101 | CMPSWP | Compare-and-swap with ptr, old_val & new_val on stack.     |
+| 000110 | TEST   | Pop TOS and set PSW according to value.                    |
+| 000111 | BRZ    | Pop TOS & NOS. If NOS==0, then set PC to TOS value.        |
+| 000010 | LOAD   | Pop address from TOS, dereference and store to TOS.        |
+| 000011 | STORE  | Pop address from TOS, pop data from NOS, deref and store.  |
+| 000001 | NOP    | Do nothing.                                                |
+| 000000 | HALT   | Halt the CPU.                                              |
+
+The Instruction Reference contains a more complete description of these operations.
+
+Processor State
+---------------
+
+The Processor Status Word (PSW) contains *N*egative and *Z*ero flags in the
+following bit positions.  See the Instruction Reference for details on which
+operations set these flags.
+
+    +-------+------------+-----+-----+
+    |  Bits |    31..2   |  1  |  0  |
+    +-------+------------+-----+-----+
+    | Flags | Unassigned |  N  |  Z  |
+    +-------+------------+-----+-----+
+
+In addition to a traditional Program Counter (PC), the processor also includes
+a Syllable Counter (SC) which ranges from 0 to 4. Both the PC and SC point to
+the next instruction to be executed. Thus, when executing the middle syllable
+of a word located at address 0x200, the PC is 0x204 and the SC is 3.
+
+Since the CPU is stack based, it includes a Stack Pointer (SP).

+# KEBA - A Keyboard #
+
+The goal is a keyboard suitable both as a general purpose UNIX workstation
+keyboard and as a NED keyboard. The project name is KEBA.
+
+## Size ##
+
+Picture a rectangle from the bottom-left `Control` key to the upper right
+`Backspace` on a traditional 104-key keyboard. That entire block is the *core*.
+
+When my hands leave the core, it is as disruptive to my typing as when I reach
+for the mouse. Thus, the new keyboard will only be the size of the core. In
+order to utilize the large number of pre-existing keyboard cases and
+accessories, I will target the "60% keyboard" size, mounting holes and connector
+location.
+
+## Layout ##
+
+The single, universal piece of advice I have received is that, if I want to
+retain my muscle memory for a traditional keyboard, my alterations must not be
+minor. Only a significant break from a traditional layout will allow my brain
+to train a new set of memories without meddling with the old set.
+
+I'm going to follow that advice.
+
+### Physical Layout ###
+
+Many of the keys accessible on a traditional keyboard via extending my pinky
+finger (think: `-=[]\'/.`) are difficult to hit accurately. I consistently end
+up one key off when trying to enter any kind of brace (`(){}[]`). However, my
+pinky was able to easily navigate the block of function keys adjoined to the
+left side of the keyboard core on a Sun keyboard.
+
+As those Sun keys are laid out in a grid, a pure ortholinear layout seems
+logical.  This also plays into the 'sufficiently different' criteria. By
+forcing my fingers to move to unaligned (w.r.t. a traditional keyboard)
+locations, my brain should switch back to traditional layout when presented
+with a staggered keyboard.
+
+Since the block Sun adjoined was a 2x5 grid and the upper-most and lower-most
+keys were at the edge of comfort, we will go with five rows. This fits cleanly
+into the 60% keyboard case.
+
+Although a 60% case will allow 15 columns of keys, it was difficult to
+accurately place my hand on top of the outermost function keys, instead
+frequently sliding over the key while pressing it down. To avoid this, remove
+one column of keys and make the two outermost columns 1.5u wide.
+
+After analyzing my keystrokes by lightly marking the top of my keys, I
+discovered that my spacebar is only struck over a surface corresponding to 2.5
+key widths. Given the ortholinear layout, we will reduce the spacebar to 2u
+wide and include multiple 2u buttons.
+
+Putting together the current criteria, we arrive at the following layout:
+
+![](/projects/ned/keyboard_images/001_kb_img.png "")
+
+### Logical Layout ###
+
+We first consider the alphanumerics. This consists of a 10x4 grid with four
+empty spots (the `;/.,` keys). When placing it into the 12x4 space available,
+split it to allow for a wider spread of the hands, creating an easier angle on
+the wrists. This also avoids a double column of utility keys on the outer ends
+of the board, instead moving one column from each side into the middle and
+making it easier to accurately hit the pinky-associated utility keys.
+
+The alphabetic keys will reside in a modified Colemak configuration with the
+`U` key moving down two spots, just to the right of the `M` key, and the `O`
+key moving to the `U` key's old location. This modified Colemak layout allows
+placement of `Escape` directly underneath the right pinky.
+
+While we're at it, rearrange the numbers into the correct order.
+
+That thinking generates this alphanumeric+`Escape` core layout:
+
+![](/projects/ned/keyboard_images/002_kb_img.png "")
+
+The remaining special keys are
+
+    Tab, Shift, Control, Alt, Space, Enter, Backspace.
+
+Since `Backspace` is never pressed in the course of regular typing, we locate
+it at middle-top where each index finger can reach it with a small stretch.
+Given their frequent use, `Space` and `Enter` are placed under the thumbs.
+`Shift` moves to the most convenient pinky location. Then `Tab` is placed
+underneath that location, still easily accessible but the least accessible of
+the `Ctrl`/`Shift`/`Tab` combo.
+
+My computing environment uses `Alt` to send instructions to the operating
+environment and `Control` to send instructions to individual programs.
+Consequently, we place `Control` to the left of the `QWFPG` row for convenient
+use with the left side alphabetic keys and place `Alt` bottom-center so the
+entire keyboard is easily reached while it is depressed.
+
+In practice, I found that I never use the right hand `Alt`, `Shift` or
+`Control` so there will be only one of each on this keyboard.
+
+Arrow keys are assigned under the assumption that up/down arrow keys should not
+share a hand with `Enter` since one frequently pages through a list with
+up/down arrows and selects with `Enter`, like when selecting a command from the
+command line history. By keeping them on separate sides of the board, both
+hands can be used.
+
+The four corner keys will be reserved for user-programmable shortcuts.
+
+That leaves us with the following layout:
+
+![](/projects/ned/keyboard_images/003_kb_img.png "")
+
+Finally, all the remaining keys will be mapped via four overlays, selectable
+via two Meta keys on the bottom row. Holding a combination of these keys down
+will select the overlay. A single tap of the key will enable the overlay for a
+single additional keypress. A double-tap of the key will lock the overlay on,
+or turn it off.
+
+Via this mechanism, the remaining 12 blank keys can encode 48 values.
+
+Importantly, overlays will NOT change any keys other than these 12 blank keys.
+Every key in the following set will remain unchanged in every overlay:
+
+    a-z, 0-9, Control, Shift, Alt, Tab, Space,
+    Enter, Backspace, Arrows, Escape, Meta1, Meta2
+
+At a minimum, the overlays need to include the following characters from a
+standard 104-key:
+
+    `~!@#$%^&*()_+-=[]{}\|;:'",.?/<>
+
+Including other characters, say some logic and set theory symbols, is enticing
+but would require a custom keyboard definition in each OS I use. Perhaps
+careful assignment of keycodes so as to stay outside the standard 104-key
+definitions would allow a 'compatibility' mode. For that reason, I would like
+to keep the combined (`Meta1`+`Meta2`) overlay blank, if possible.
+
+Assignment of the overlay keys is still tentative.
+
+I know I want all the brackets down the middle. The remaining assignments are
+made in consideration of the key's frequency of use in/at normal English
+writing, the UNIX command line, and the C programming environment.  Allowing
+overlap, I see those sets as follows.
+
+English Language:
+
+    !,.?
+
+UNIX Commandline:
+
+    `~&*_-\/|"
+
+C Language:
+
+    #&*-+=;:'",/
+
+Other:
+
+    @$%^
+
+When assigning overlays, since the 'extra' overlay buttons are on the right
+hand side, the left overlay button, or `Meta1`, should take precedence over the
+right overlay button. In other words, the priority should be:
+
+    Default > Meta1 > Meta2 > Meta1+Meta2
+
+The following are the three overlays as currently assigned:
+
+![](/projects/ned/keyboard_images/004_kb_img.png "")
+
+![](/projects/ned/keyboard_images/005_kb_img.png "")
+
+![](/projects/ned/keyboard_images/006_kb_img.png "")
+
+## Keyswitches ##
+
+In the linear vs clicky vs tactile decision, my *normal* is most people's
+*extreme*. I consider an IBM Model M to be the baseline for an adequate
+computer keyboard, not some ultimate endpoint.
+
+The switches most frequently recommended for someone that likes the Model M are
+the Cherry MX Greens. I already use MX Blues from the same family to repair
+Tektronix terminals and find the tactile style suitable. If the information on
+the internet is to be believed, MX Greens are still lighter than a Model M but
+are the heaviest MX-series switches on the market.
+
+It might make sense to install Mill-Max sockets in one PCB so I can easily swap
+keyswitches until I find what I want, despite the cost. Even if the MX Greens
+are where I settle, I won't know they're *right* until I also try some other
+switches.
+
+## Keycaps ##
+
+Keycaps should be either the full SA profile, or all SA Row 3 profile.
+Alphanumeric caps should have a SINGLE character on them, not a double printing
+that includes the 'shifted' character. All overlay and most non-alphanumeric
+caps like Space and Enter should be blank. Meta keys can be playful, consider
+PLOT/STOP or BREAK/RESET from my existing keycap inventory.
+
+## Computer Interface ##
+
+Since both QMK and the STM32 natively support USB, that is a natural interface
+to choose.
+
+Alternatively, I could expose a logic level UART and design a series of inline
+dongles to convert to whatever signalling I want. That allows me to easily
+connect the keyboard in place of a USB, PS/2, Sun Type 3 & 5, Tektronix
+terminal, etc keyboard. This option would require custom firmware.
+
+## Human Interface ##
+
+The keyboard should include LED lights behind the keys for use in communicating
+with the user. By default, the lights should be off and should only briefly
+light to communicate. At a minimum, there should be a different blink for each
+Meta key to indicate when it is triggered/toggled. Perhaps multi-color LEDs to
+indicate the different overlays?
+
+If using USB, expose a virtual UART to the host that allows for configuration.
+If using a generic UART, configure the keyboard to enter a programming mode on
+that same UART when some contrived combination of keys is pressed. Either way,
+the keyboard should be easily configurable via a human-readable UART interface.
+
+## Firmware ##
+
+If I use a USB interface, I can copy my STM32 circuit from Liquid Fusion and
+use it with QMK until I get around to writing my own code. Will QMK support the
+'toggle by double-tap' feature I envison for the Meta keys?
+

+# NED - Simulator #
+
+A simulator, assembler, disassembler and graphical front panel implementing NED
+v1. Browse the [source
+code](http://gitweb.subgeniuskitty.com/?p=ned-v1-simulator/.git;a=tree).
+
+## Status ##
+
+The assembler, disassembler, and front panel are fully functional. The CPU
+simulator only supports a single CPU and does not implement the `CMPSWP`
+instruction but is otherwise functional.
+
+The calculator included as an example of NED assembly is also fully functional.
+
+## Getting Started ##
+
+Obtain a snapshot of the repository.
+
+    wget -O ned.tgz "http://gitweb.subgeniuskitty.com/?p=ned-v1-simulator/.git;a=snapshot;h=HEAD;sf=tgz"
+    tar xzf ned.tgz
+    cd ned-v1-simulator-HEAD*
+
+Build all the tools by executing `make` in the top-level directory or use
+`make` in individual project subfolders. Note that `nedfp` requires SDL2 and
+SDL2_ttf but is not required for simulation.
+
+No `install` targets are supplied for `make`. Instead, manually copy the
+binaries wherever you want or adjust your `$PATH` to use them in place. For example:
+
+    export PATH=/home/username/ned/nedasm:/home/username/ned/nedsim:$PATH
+
+Once the NED binaries are accessible from your `$PATH`, the calculator example
+can be run with `make sim`. Exit with `Ctrl-C`.
+
+    cd software/4func_calculator
+    make sim
+    <calculator starts up and takes control of the screen>
+
+To use `nedfp` as a graphical front panel for debugging, first start `nedfp`
+with no arguments. Then, execute `nedsim` with flags for IP address and port.
+The `-s` flag can be useful in slowing the simulation down enough to understand
+`nedfp`'s output.
+
+    nedfp/nedfp &
+    nedasm/nedasm -i software/4func_calculator/calc/asm -o /tmp/calc.bin
+    nedsim/nedsim -i /tmp/calc.bin -a 127.0.0.1 -p 4999 -s 10000
+
+Binaries can be disassembled with `neddis`. Using the calculator as an example:
+
+    % ./neddis/neddis -i ./calc.bin -s -l

+# Overview #
+
+I've started using my PDP-11 for instrument control and wanted faster floating
+point (FP) calculations. My PDP-11/83 is based on the DCJ11 chipset which
+provides a microcoded implementation of the PDP-11 FP instructions. However,
+there was a hardware FP co-processor, the FPJ11, that was designed to work with
+the DCJ11 and provides a 5x-8x speedup on FP operations. Unfortunately, the
+documentation contains a few references that made me hesitant to simply
+purchase an FPJ11 and plug it in.
+
+For example, DEC Micronote #25 mentions that
+
+    An FPJ11-AA installed on a KDJ11-AA may APPEAR to work
+    but cache errors and parity errors may occur.
+
+Yikes!
+
+What follows is the compatibility information necessary to add an FPJ11 to a
+DCJ11-based PDP-11. It has been condensed from various USENET postings and DEC
+manuals.
+
+# DJC11/FPJ11 Compatibility #
+
+Commercially released DCJ11 chipsets ran at either 15 or 18 MHz and there were
+two versions of the FPJ11 to match. The part number is written on the gold
+cover in the middle of the ceramic package. If you have an 18 MHz DCJ11 but can
+only find a 15 MHz FPJ11 it is possible to change the crystal on the CPU board
+to 15 Mhz. This would require an extremely FP-heavy workload to be worthwhile.
+
+|    FPJ11    |  Speed |
+| ----------- | ------ |
+| 21-21858-05 | 15 MHz |
+| 21-21858-06 | 18 MHz |
+
+In addition to clock speed, the earliest DCJ11s must be avoided as they are
+simply incompatible. This part number is located on the white ceramic package,
+between the DC334 Data chip and DC335 Control chip.
+
+|    DCJ11    |  Speed | FPA Compat? |
+| ----------- | ------ | ----------- |
+| 57-19400-04 | 15 MHz |      No     |
+| 57-19400-08 | 15 MHz |     Yes     |
+| 57-19400-09 | 18 MHz |     Yes     |
+
+
+# KDJ11 CPU Board Compatibility #
+
+
+Excluding the PDP-11/53 CPU boards that lack a socket for the FPJ11 and the
+PDP-11/93 CPU board that always includes the FPJ11 leaves us with the following
+set of CPU boards from the PDP-11/73 and /83 that are potential FPJ11
+recipients.
+
+| KDJ11-xx | M819x-xx | FPA Compat? | Notes                                                                                      |
+| -------- | -------- | ----------- | ------------------------------------------------------------------------------------------ |
+| KDJ11-AA | M8192    |      No     | DEC uNOTE #25 states this board was upgradeable. Some FPJ11-compatible versions may exist. |
+| KDJ11-AB | M8192-YB |     Yes     | When the FPJ11 is installed this board magically becomes an M8192-YC/KDJ11-AC.             |
+| KDJ11-BC | M8190    |      No     |                                                                                            |
+| KDJ11-BB | M8190-AB |     Yes     | When the FPJ11 is installed this board magically becomes an M8190-AC/KDJ11-BD.             |
+| KDJ11-BA | M8190-AD |     Yes     | When the FPJ11 is installed this board magically becomes an M8190-AE/KDJ11-BF.             |
+
+# FPJ11 Testing #
+
+When the KDJ11-B detects an installed FPJ11 it flags bit 8 (counting from 0) in
+the Maintenance Register located at `17 777 750`. Using ODT to test on a
+freshly powered up Qbus system with FPJ11 installed:
+
+    @17777750/000445
+
+And on the same system with the FPJ11 removed:
+
+    @17777750/000045
+
+Note that your results may be different since this register also encodes
+Unibus/Qbus, KDJ11 module type, BPOK status, power up mode, and halt/trap
+options. Exact details can be found in the KDJ11-B CPU Module User's Guide
+(EK-KDJ1B-UG-001) starting on page 1-43.

+    Introduction
+    
+        This  list is  an attempt to coalesce all net knowledge on PDP-11
+        UNIBUS and  Qbus modules.  It is  designed to  supercede all  the
+        various homespun lists floating around -- giving one solid source
+        of information.
+    
+        An expansion  is in  progress.  In addition  to PDP-11 UNIBUS and
+        Qbus,  the list  will now cover other forms of the PDP-11 such as
+        the Professional  Series (CTI-Bus).  Further,  it will  cover not
+        only PDP-11s,  but VAXen and MIPS  systems as  well (VAXen  being
+        available in  both UNIBUS  and Qbus  forms,  and MIPS machines in
+        Qbus).  The list  will also  begin to  include chassis,  mounting
+        boxes, power supplies and backplanes.
+    
+        For some  non-Digital (third-party) disk and tape controllers,  a
+        list of reputedly compatible  drives may  be shown.  This list is
+        not exhaustive,  and other  similar disk  and tape interfaces may
+        also work.
+    
+        This list may be found on the following sites:
+    
+         1) http://world.std.com/~mbg/pdp11-field-guide.txt
+    
+       As of 02-Feb-2000, when I accepted the offer from the former
+       maintainer to take over the file, this copy has become the
+       official, most up-to-date copy.  One thing people may note is
+       that I have renamed it.  This is because there is a similar
+       file in the works elsewhere to cover pdp8 modules and options.
+    
+       Comments and suggestions about the format and content of the
+       file will be welcome at all times.
+    
+       Please note that it may take some time for the *new* official
+       file to make it to the mirrors mentioned below.
+    
+         2) On metalab.unc.edu, in the following location:
+       /pub/academic/computer-science/history/pdp-11/hardware/field-guide.txt
+    
+       Tim maintains quite a large archive of other information, it
+       is most definitely worth checking out -- Thanks, Tim!
+    
+         3) On ftp.village.org, in /pub/pdp-11/field-guide.txt
+    
+            Dworkin keeps a compressed version here, too.
+     
+         4) On ftp.update.uu.se in /pub/pdp11/doc/field-guide.txt
+    
+            Johnny's site has quite a plethora of PDP-11 stuff, along with
+            files/software pertaining to Pros and DECmates.
+    
+    
+        This file will be posted on an irregular basis to the PDP-11 related
+        newsgroups (vmsnet.pdp-11, alt.sys.pdp11). 
+    
+        In order to ensure that this file is as comprehensive and accurate
+        as possible, please don't hesitate to:
+    
+       1) Send any additions or corrections you may have to the
+          file maintainer (currently mbg@world.std.com).
+    
+       2) Feel free to edit a private copy of the file to include
+          your additions or corrections and send it (or a differences
+          file) to the file maintainer.
+    
+        Please be prepared to cite the source of any such information.  This
+        is to ensure that the file contains only validated information.
+    
+        Just make sure you send anything you have to me. If you have
+        relevant hardcopy and you don't feel like typing it in, get in
+        contact with me and we'll work something out.
+

+    
+        We owe a great amount of thanks to Tim Shoppa, Johnny Billquist,
+        Dworkin Muller and all others who maintain PDP-11 ftp sites.  Also,
+        a great deal of respect is to be accorded to *anyone* attempting to
+        hook a PDP-11 to the net, or running one currently connected, for
+        that matter.  The same for anyone, anywhere who *doesn't* put a
+        PDP-11 into the dumpster.  Or the smelter. Etc.  If you don't know
+        what to do with it, please contact me via email and we'll get the
+        information out to people who would be interested in saving it.
+    
+        We owe final credit and gratitude to Ronald Copley, who developed

+    Notes:
+    
+       o 'Refs:' indicates documention in which information for the
+         option may be found.
+    
+       o In the BUS column, Q is Qbus, U is UNIBUS, CTI is CTI bus
+         (Professional 300 series).  With Vax and MIPS boards being
+         added, there may be some new bus designations such as BI
+         and XMI added here.
+    
+       o EK-xxxxx-yy numbers are documents, with yy = UG for
+         user guide, TM for technical manual, IN for installation
+         manual, RC for reference card, OP for operator's manual,
+         PS for pocket service guide, CG for configuration Guide.
+         (These are only a few examples, not a definitive list).
+         The 'xxxxx' is often, but not always, the option name.
+    
+       o MP-xxxxx numbers are maintenance printsets
+    
+       o ZFxxx-RZ and ZJxxx-RZ numbers are Diagnostic Documentation
+              Kits.
+    
+       o The Micronotes (uNotes) are single-topic articles, written
+         by various people within Digital to clarify information for
+         other Digital employees.  There are two sets of them, with
+         similar numbers.  If a uNOTE is cited here, it should be
+         listed as either uNOTE O# to signify the original set of
+         115, or uNOTE N# to signify the newer set of 44.  Some of
+         the older uNotes were recycled and given new numbers.  Check
+         out metalab.unc.edu for copies of the new Micronotes, which
+         can be found under:
+    
+         /pub/academic/computer-science/history/pdp-11/hardware/micronotes
+    
+       o For Qbus boards, unless specified as having an S-Box handle
+         or being a MINC module or for a BA200 series enclosure, boards
+         should be able to be used in any Qbus backplane.  (In fact,
+         most boards without S-Box handles should still be usable in
+         a BA200 series enclosure)
+    
+       o Please note that some Qbus modules may only be inserted into
+         Q/Q backplanes, some may only be inserted into Q/CD backplanes,
+         and some are jumper selectable for Q/Q or Q/CD.  Also, some
+         modules support 16-bit only, some support 18-bit and some
+         support full 22-bit.
+    
+       o The latest version of the file has been modified such that
+         for a given module, all lines containing text pertaining
+         to that module have the module number at the beginning of
+         the line.  This is to make it easy to grep (UNIX) for a
+         module number and have all information returned instead
+         of just the first line.

+# Overview #
+
+Although GCC claims to support PDP-11 targets there are some bugs that must be
+worked around both in GCC and the GNU assembler.
+
+# GNU binutils Bugs #
+
+## Problem Description ##
+
+One of the addressing modes supported by the PDP-11 is 'index deferred',
+represented by `@X(Rn)`. This operand indicates that `Rn` contains a pointer
+which should be dereferenced and the result added to `X` to generate a new
+pointer to the final location. For example, consider the following four values,
+one stored in a register and the other three in memory. Then `@2(R1)` is the
+value `222`.
+
+    R1: 1000
+    1000: 2000
+    2000: 111
+    2002: 222
+
+Similarly, `@0(R1)` is the value `111`. In most PDP-11 assemblers, including
+DEC's MACRO-11 assembler, the string `@(Rn)` is an alias to `@0(Rn)`. But when
+the GNU assembler encounters `@(Rn)` it assembles it as though it were `(Rn)`,
+a single level of indirection instead of two levels!
+
+If we're only writing assembly then we can work around this bug by always using
+the form `@0(Rn)`. But what if we're writing C and using GCC to compile it?
+Consider the following C code example, taken directly from some stack-based
+debugger code written for the PDP-11.
+
+    uint16_t ** csp = (uint16_t **) 070000;
+    *csp = (uint16_t *) 060000;
+    **csp = 0;
+
+When GCC transpiles this to assembly it generates code of the form `@(Rn)` when
+assigning a value to `**csp` thus causing the value `0` to overwrite the value
+`060000` at `*csp` if GNU `as` is used to assemble the code.
+
+## Solution Description ##
+
+The following patch, tested on GNU binutils 2.28, fixes the bug. Since it
+overloads the `operand->code` variable to pass unrelated state information to
+`parse_reg()` I haven't submitted it for inclusion in GNU binutils. Once I'm
+done bug-hunting in my toolchain I will clean up all the fixes and submit them
+in one bundle.

+# Overview #
+
+Sun has a long history of introducing artificial compatibility restrictions between similar systems in order to drive increased sales. The Sun Blade 1000 officially supports 600, 750 & 900 MHz CPUs while the Sun Blade 2000 supports CPUs up to 1.2 GHz. It would be a nice speed boost for my Blade 1000 if I could use the faster CPUs.
+
+An internet search turned up conflicting information. Some people claimed the CPU upgrade should work, while others claimed it would be incompatible or cause problems with overheating. No one reported actually trying the upgrade, so all posts were mere speculation. An examination of the Sun System Handbook reveals identical part numbers (501-6230, 501-5938 & 501-4143) for the system boards of the Blade 1000 and 2000. The internal layout and cooling of the two systems is also identical. Furthermore, the two systems share one officially compatible CPU, the 900 MHz UltraSPARC III Cu (501-6002), indicating that the Blade 1000 does support the later Cu modules. In theory, the faster CPU should be a drop-in replacement, requiring at most a firmware upgrade.
+
+I attempted the upgrade and it went smoothly. The information below documents my attempt. Although YMMV, I suspect this upgrade will work for all combinations of CPUs and system boards used in the Sun Blade 1000, Blade 2000, SunFire 280R and Netra 20. 
+
+# Hardware #
+
+The exact hardware used for this test is shown below. If you attempt this procedure, let me know what part numbers you used and the result; I will update this page.
+
+    System Board: 501-6230
+             CPU: 501-6750
+            PROM: 4.16.4 (patch 118323-01)
+
+My computer originally had OBP v4.10.1. The upgrade to 4.16.4 is in patch 118323-01 which I have included as a link at the bottom of this page. It can be applied either from within Solaris or directly from your existing OBP environment via a UFS volume. Instructions for both methods are included in the tarball. Remember to set the write-enable jumper on the system board.
+
+If you transition from dual to single CPU the empty slot must be filled in order to maintain proper airflow, but original filler panels are difficult to find. A plug could be made out of cardboard but, if you have dead CPUs available, removing the connector allows use of an old CPU, thus ensuring proper airflow. A table saw cuts through PCB like a hot knife through butter. Clean the edge thoroughly; you don't want to introduce metal flakes inside your Blade 1000. Also, use spacers on the anchor bolts of the CPU to prevent contact and damage to the connector on the system board.

+# Overview #
+
+While listening to shortwave, I noticed that huge chunks of the spectrum were being swamped at certain times of day. Since my spectrum analyzers are all analog, I decided to write a quick script to allow use of the HP 3586 selective level meter as a rudimentary spectrum analyzer.
+
+%%BEGIN_GALLERY%%
+hp_3586_gpib_spectrum_analyzer.files/hp3586_specan_squarewave.png|A quick test, 200 Hz square wave.
+hp_3586_gpib_spectrum_analyzer.files/hp3586_specan_publicspectrum.png|Local spectrum, no stations active.
+hp_3586_gpib_spectrum_analyzer.files/hp3586_specan_publicblanket.png|Tail end of noise source. Note that the horizontal axis is both time and frequency due to the length of time required to sweep.
+hp_3586_gpib_spectrum_analyzer.files/hp3586_specan_publicblanket_3d.png|161 hours of listening. Vertical axis is UNIX timestamps. Noise source is immediately visible.
+%%END_GALLERY%%
+
+# Instructions #
+
+To use the script, edit it with a text editor and change the starting frequency ($freq_start), ending frequency($freq_end), step size($freq_increment), and number of sweeps to perform ($scan_rep). All frequencies are in kilohertz. Then, run the script and redirect output to a file. For example,
+
+    ataylor:~$ perl hp3586_specan.pl > output.data.txt
+
+After the sweep is finished you can generate 2D or 3D plots with the following gnuplot scripts. Either change the xrange and yrange to match your data or comment out the lines so gnuplot autoscales each axis.
+
+    # 2D Plot

+The source code below contains two sleep() statements. You can reduce them in order to perform a faster sweep, but reducing them too far will cause odd behavior when the 3586 is not yet ready to supply a reading at the new frequency. As an example, it took just over two hours for a sweep from 9.25-10.25 MHz in 1 kHz steps with a 3.1 kHz RBW and sample averaging, as shown in the sample data file on this page.

+# Overview #
+
+The HP TS-510A/U is the military version of the HP 608D signal generator. Other than some physical differences such as waterproof switches, different power connector and built-in locations for spare fuses, it appears identical to the HP 608D.
+
+I acquired this unit locally, together with a Tektronix 545 for $20. Despite sitting in a drafty shed for years it powered up, output reasonable signals and responded correctly to all controls. It's always nice to have a second signal generator so I decided to restore this unit and put it to use.
+
+## Diagnosis ##
+
+The first problem was a 60 Hz modulation of the output that was ripple from inadequate power supply filtering. Testing showed every electrolytic capacitor to have excessivly high leakage.
+
+In each of the photos below, the bottom trace is the modulated RF output and the top trace is the modulating signal of 400 Hz. The 60 Hz ripple can be seen as a gradual drop in the first image and is clearly visible as a 60 Hz sine wave modulating the output in the second image.

+
+## Repair ##
+
+Unlike silicon rectifiers which have a forward voltage drop of approximately 1.7 V, selenium rectifiers have a much larger forward voltage drop. For the rectifiers in this instrument it measured 20-30 V. If a direct replacement of silicon for selenium is made, that excess voltage must be dropped by the regulator tube in the power supply, likely exceeding its plate dissipation rating and shortening its lifespan.
+
+To solve this problem we will include series resistors on the output of each bridge rectifier. The voltage drop across the resistors will vary with load, so we choose a resistance such that, at maximum power draw, each regulator tube has a 2% voltage overhead before losing regulation. Under lesser loads the regulator tube must drop more voltage but will have correspondingly less current to deal with.
+
+It is important to note that a few of the replacement capacitors will have bodies which are at a different potential than ground. The original capacitors solved this problem by using paper bodies. I don't know the voltage rating of the plastic wrap on the capacitors so I gave them an additional wrap of 600v heatshrink.

+
+## Results ##
+
+After the repair all power supplies are within spec and have sub-1 mV ripple. Sample output signals are shown below; all traces of 60 Hz ripple are gone.
