The PDP-11/04 was a mid/late-70s implementation of the PDP-11 architecture for the UNIBUS; it was a replacement for the PDP-11/05. It was implemented on a single hex card (M7263), the first PDP-11 CPU to be contained on a single board.
It was the first PDP-11 to come standard without a 'proper' lights and switches front panel: the standard KY11-LA Operator's Console front panel had only 'Boot/Init', 'Halt/Cont', and power switches, and the system came with an M9301 ROM card which included a console emulator, which communicated through the console terminal.
DEC did offer the KY11-LB Programmer's Console as an option for the -11/04; it had an octal keypad, the usual 'Halt'/'Start'/etc keys, and a 6-digit LED display which showed address/data digitally.
It came in two chassis configurations: the BA11-L half-height box, which had the entire computer - card guide frame, backplane, power supply, and front panel - sliding into an evil jamming finger-trapping metal sleeve; and a full-height example, basically the same BA11-K box as used throughout the PDP-11 line. (This is very similar to its higher-spec twin, the PDP-11/34.)
Registers
Like its predecessor PDP-11/05, the general registers (R0-R5, SP and PC) have addresses assigned to them, which makes them accessible from the KY11-LB Programmer's Console when the machine is halted. Their addresses are:
| Address | Register |
|---|---|
| 777700 | R0 |
| ... | |
| 777705 | R5 |
| 777706 | SP |
| 777707 | PC |
Note that the register addresses, like those on the -11/05, increment by 1, not by 2, as is usual for word-sized items.
In addition, four internal CPU registers which record the CPU's most recent memory operations are also available:
| Address | Register |
|---|---|
| 777710 | Source address |
| 777711 | Source data |
| 777712 | Destination address |
| 777713 | Destination data |
