PDP-8 Simulator Configuration
</H1>
<P>
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):
