 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.
