PDP-11/05 | |
Manufacturer: | Digital Equipment Corporation |
---|---|
Architecture: | PDP-11 |
Year Introduced: | June 1972 |
Word Size: | 16 bit |
Physical Address Size: | 18 bits (only 16 bits usable) |
Bus Architecture: | UNIBUS |
The PDP-11/05 was the fourth model in the PDP-11 series, following the PDP-11/20, the PDP-11/45 and the PDP-11/40; it used the KD11-B CPU. It was intended as a cost-reduced low-end machine to replace the PDP-11/20. Like all the other early PDP-11's, it was a UNIBUS machine.
The PDP-11/05 was absolutely identical to the PDP-11/10; the only difference between the /05 and the /10 was the number printed on the front panel. The /05 was aimed toward the OEM market, while the /10 was intended for end-users. General usage (following DEC's lead) is to refer to all these machines as '11/05's.
The earliest units came in a 5-1/4" box, which had room for only a double system unit backplane. A later version, the /05N and /10N, came in a 10-1/2" BA11-D Mounting Box; the final /05S and /10S versions came in the 10-1/2" BA11-K Mounting Box.
Backplane versions
The PDP-11/05 and /10 came in three versions, with four different versions of the main backplane (the 9-slot system unit holding the two CPU cards). All have two slots for the KM11 card, plugged in to debug the CPU; each slot is numbered with the correct KD11-B KM11 overlay for a KM11 in that slot. (The KM11 switches function identically in both slots.)
Original version
The original /05 and /10 came with backplanes wired to hold MM11-L 16 Kbyte core memory units. There were two different backplanes (all four backplanes are un-named, but the part numbers, given below, are etched into the large PCB on each).
One, (called "Configuration 1" in DEC documentation, backplane part #5410035), held two memory units, with one slot left for quad-height SPC devices. The other ("Configuration 2", backplane part #5409818) held one memory unit, and provided four SPC slots; it could also hold a DF11 Communications Line Adapter to convert the asynchronous serial line console line to EIA RS-232.
Here are the slot assignments in the backplanes (as seen from the board insertion side of the backplane, not the wire-wrap pin side, as is common in DEC documentation) :
Configuration 1:

6 | Unused | SPC | ||||
7 | UNIBUS Out | SPC | ||||
8 | KM11-1 | KM11-2 | SPC | |||
9 | DF11 | SPC |
Note that the slots are numbered from 1 at the start; this is the inverse of the numbering for these backplanes in some DEC documentation.
-N type
The /05N and /10N had a slightly different backplane (part #5410329; the complete unit has been observed labelled "Type: 10 5K", "Part No.: 70-09241"). This had space for two MM11-L memory units, but deleted the SPC slot of the previous double MM11-L backplane, and replaced it with a slot to hold the dual-height M9970 console terminal cable board, and also a dual-height DF11.
Board locations (again, as seen from the board insertion side of the backplane) are:
Connector | ||||||
---|---|---|---|---|---|---|
Slot | A | B | C | D | E | F |
1 | DF11 | M9970 | KM11-A | KM11-B | ||
2 | M7260 CPU board #0 | |||||
3 | M7261 CPU board #1 | |||||
4 | UNIBUS Terminator | H213/H214 Core stack | ||||
5 | G110 Memory Control | |||||
6 | G231 Memory Driver | |||||
7 | G110 Memory Control | |||||
8 | G231 Memory Driver | |||||
9 | UNIBUS Out | H213/H214 Core stack |
Note that the two KM11 slots are at the other side of the backplane from the slots used for them in the 'Configuration 1' and 'Configuration 2' backplanes.
-S type
The /05S and /10S came with a backplane (part #5410972, complete assembly part #70-09921) wired to hold an MM11-U 32 Kbyte core memory, and which provided three SPC slots. The layout (from the board insertion side) is:
Connector | ||||||
---|---|---|---|---|---|---|

2 | M7261 CPU board #1 | |||||
3 | UNIBUS Terminator | SPC | ||||
4 | DF11 or M9970 | SPC | ||||
5 | KM11-1 | KM11-2 | SPC | |||
6 | G235 X-Y Drive | |||||
7 | H217-D Core Stack | |||||
8 | G114 Sense/Inhibit | |||||
9 | UNIBUS Out | M8293 Memory Control |
Keys
Unlike all the other keyed PDP-11s, which use a cylindrical Ace key, the /05's (and /10s) use a normal flat Yale-type key. The original key is a Chicago Lock Company key, code "GRB 2"; this is cut 215, on a Chicago K5K or Ilco S1041T blank. (It has been confirmed that a locksmith was able to produce a working key from this information.) If simply duplicating an existing key, Hillman Y11 and FR4 blanks may be used (both work, but one has to be trimmed a bit, length-wise).
