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 [[KY11-J Programmer's Console]]). The /05 was aimed toward the [[Original Equipment Manufacturer|OEM]] market, while the /10 was intended for [[end-user]]s. 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]]. (Additional memory was initially indicated to require the use of an [[MM11-L core memory|ME11-L]] memory unit; similarly, a [[BA11-E Mounting Box]] was initially indicated as required to hold any [[device controller]]s beyond the limited number the [[Central Processing Unit|CPU]] backplane would hold. Alternative solutions to both were of course possible.) The [[power supply]] of this box does not have an 'Hxxx' assembly identifier, only a [[DEC part number]]: 70-08731; and 54-09728 for the DC Regulator Module.

A second version, the /05N and /10N, came in a 10-1/2 inch box and had a slightly different backplane, which 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 [[DEC card form factor|dual-height]] M9970 console terminal cable board.

The later /05S and /10S came with a backplane wired to hold an [[MM11-U]] 32 Kbyte core memory, and which provided three SPC slots.

One, (called "Configuration 1" in [[Digital Equipment Corporation|DEC]] documentation, backplane part #54-10035), held two memory units, with one slot left for quad-height [[Small Peripheral Controller|SPC]] devices. The other ("Configuration 2", backplane part #54-09818) 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 serial line interface|EIA RS-232]].

The two boards in the PDP-11/05-10 (the M7260 data paths module, and the M7261 control logic module) both come in two markedly-different versions, but unlike later practise (as in, e.g. the [[PDP-11/34]]), the two versions are not given different M-numbers, or clearly marked with a revision (i.e. 'M7260' and 'M7260-AA') on the handles.
+
Configuration 1:
  
−
One easy way to visually distinguish the early M7260 from later ones is that the later ones contain a circular selector switch in the upper left corner to select the baud rate of the built-in serial line; also, the position of the large [[UART]] chip has a different location (from down near the contact fingers, to up near the handles) and orientation (parellel to the board's long axis, in the earlier revision). For the M7261, the early version of the board has a large blank area, containing only traces, in the left middle area of the board.

The early revision of the M7260 is the 'B' revision; the later is the 'C' revision (the latter is marked as such, on the back side of the board- "M7260C"). For the M7261, two early revisions are the 'C' and 'E' revisions (the latter also similarly marked - "M7261E"); the later is the 'F' (also marked).

The early version of the M7260 only supports 110 baud operation; the latter has a circular selector switch which allows operation at a range of speeds from 110 baud up to 2400 baud; however, it is necessary to tweak a trim pot to change from the 110/220/440/880/1760 speed set to the 150/300/600/1200/2400 set.

The later revision of the M7261 contains two jumpers which are not present on the earlier revision. One (W1) disables to built-in serial line (which is 20mA, and limited to 2400 baud), allowing use of a more capable serial interface as the system console. The other (W2) disables the CPU from acting as a bus arbitrator, so that the machine can be a 'slave' processor, on a UNIBUS controlled by another CPU.

PDP-11/05
Pdp11-05.jpg
A PDP-11/05 in a 'low-boy' rack, from a sales brochure
Manufacturer: DEC
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 KY11-J Programmer's Console). 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. (Additional memory was initially indicated to require the use of an ME11-L memory unit; similarly, a BA11-E Mounting Box was initially indicated as required to hold any device controllers beyond the limited number the CPU backplane would hold. Alternative solutions to both were of course possible.) The power supply of this box does not have an 'Hxxx' assembly identifier, only a DEC part number: 70-08731; and 54-09728 for the DC Regulator Module.

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 single-height slot sections 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 #54-10035), held two memory units, with one slot left for quad-height SPC devices. The other ("Configuration 2", backplane part #54-09818) 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:

Connector
Slot A B C D E F
1 M7260 CPU board #0
2 M7261 CPU board #1
3 G110 Memory Control
4 G231 Memory Driver
5 UNIBUS Terminator H213/H214 Core stack
6 G110 Memory Control
7 G231 Memory Driver
8 UNIBUS Out H213/H214 Core stack
9 KM11-1 KM11-2 SPC

Configuration 2:

Connector
Slot A B C D E F
1 M7260 CPU board #0
2 M7261 CPU board #1
3 G110 Memory Control
4 G231 Memory Driver
5 UNIBUS Terminator H213/H214 Core stack
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 #54-10329; 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.

The /05S and /10S came with a backplane (part #54-10972, 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
Slot A B C D E F
1 M7260 CPU board #0
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).
