-The '''PDP-5''' was [[Digital Equipment Corporation|DEC]]'s first 12-bit computer, the predecessor to the [[PDP-8]]. Like the -8, it was a [[load-store architecture]]. A memory extension unit was added later, to support [[bank switching]], and thus allow the use of more than 4KW of [[main memory]].

-It was built out of the standard modules created for the [[PDP-4]]. It was built using the [[bit-slice]] concept, where one bit of all the [[register]]s and the [[data path]]s between them was implemented on a single [[printed circuit board|PCB]]; a number of these boards (equal to the [[word]] length of the machine) formed the [[Central Processing Unit|CPU]]. To minimize the initial cost, it had an [[input/output|I/O]] [[bus]], rather than the radial links from the CPU to individual [[peripheral]]s used in all earlier DEC machines, such as the 18-bit machines like the [[PDP-1]].
+The '''PDP-5''' was [[Digital Equipment Corporation|DEC]]'s first 12-bit computer, the predecessor to the [[PDP-8]]; in some sense, it was DEC's first [[minicomputer]] (although the -5 pre-dated the creation of that term). Like the -8, it was a [[load-store architecture]]; its [[instruction set]] was very similar to that of the -8. A Type 154 Memory Extension Control unit was added later, to support [[bank switching]], and thus allow the use of more than 4KW of [[main memory]].
