The 12-bit PDP-8 was the first successful commercial minicomputer manufactured and sold by Digital Equipment Corporation from 1965 into the 1970s, initially designed by chief engineer Edson de Castro .
The PDP-8's basic configuration had a main memory of 4,096 twelve-bit words, the programmer's view of the PDP-8 had only eight instructions and two registers, a 12-bit accumulator, and a carry bit called the link register.
An amount of user-donated software for the PDP-8 was available from DECUS, the Digital Equipment Corporation User Society, and often came with full source listings and documentation.
