# PDP-8 Simulator Configuration

DEC's PDP-8, introduced in 1965, was the first mass produced minicomputer, as well as the first computer costing less than $20,000. It remained in active production until 1988; more than 50,000 units were produced. All the models in the family were based on one of the seven CPU designs (photographs courtesy of Digital Equipment Corporation):

- 1965: PDP-8
- 1966: PDP-8/S - serial logic design
- 1968: PDP-8/I - first design with integrated circuits (also PDP-8/L)
- 1970: PDP-8/E - first Omnibus design (also PDP-8/F, PDP-8/M)
- 1975: PDP-8/A
- 1979: Intersil 6100 - first LSI design (VT78)
- 1981: Harris 6120 - last design (DECmate I, DECmate II, DECmate III)
