Description
The PDP-8 computers were the most widely spread minicomputers of the
world. In 1978, DEC was advertising them by having sold 50.000 units
worldwide. The first version, the primary PDP8 was still assembled with
discrete transistors and had the same instruction set like the very
older PDP5. Both have 12Bit words. This comes from the original main
application of the PDP5 as a small process computer, which should
process the data from an analog/digital converter, that was
integrated in the accumulator. All PDP8 commands consist of only one
word. The minimal word length is 12 Bits, which still allows an usable
machine instruction set.
