+# Overview #
+
+A collection of tips for working with KDJ11 CPU boards.
+
+# Failed Tests #
+
+The KDJ11-B includes a variety of diagnostics in ROM that run on boot. When a
+test fails, there is a hidden option to bypass the test and continue. Simply
+press `Ctrl-O` (the letter, not the number zero), then `4`, then `ENTER`. This
+will continue on, halting at the next failed test or at the boot menu.
+
+# J11 ODT & Cache #
+
+When a KDJ11 with cache powers up, the cache is enabled by default, even in
+ODT mode. Thus, even if a memory location is faulty, writing and reading to
+that location will appear to succeed.
+
+The cache may be bypassed by setting bit nine of the Cache Control Register
+(CCR) located at `017777746`. In ODT:
