View source for PDP-12

The '''PDP-12''' was a computer produced by [[Digital Equipment Corporation|DEC]] for use in laboratory settings. It was a descendant of (and replacement for) the [[LINC-8]]; its [[Central Processing Unit|CPU]] could operate in one of two modes: either as a [[PDP-8 family|PDP-8]] (specifically a [[PDP-8/I]]), or as a [[LINC]] computer. In each mode, there is an [[instruction]] to switch to the other mode.

Like the LINC, it included a video [[display]], analog inputs, and [[LINC tape]] drives (the TC12F option allowed them to operate as either LINC tapes, or [[DECtape]]s). It could also include any of the standard PDP-8 [[peripheral]]s, attached to the positive logic PDP-8/I-type I/O bus.

The basic machine included 4K words of 1.2 microsecond [[core memory]], which could be expanded in 4K word increments to up to 32K words.
