| 14 | * 8*mbanum+drive | |
| 15 | * The mbadrv macro gives the address of the device registers | |
| 16 | * for the specified unit; the mbamba macro gives the address of the | |
| 17 | * mba registers themselves. | |
| 18 | * | |
| 19 | * The uba devices are also addressed by giving, as unit, | |
| 20 | * 8*ubanum+drive | |
| 21 | * The ubamem macro converts a specified unibus address (ala pdp-11) | |
| 22 | * into a unibus memory address space address. | |
