DEC minicomputers

The PDP-1 (Programmed Data Processor-1) is the first computer in Digital Equipment Corporation's PDP series and was first produced in 1959. It is known for being the most important computer in the creation of hacker culture at the Massachusetts Institute of Technology, Bolt, Beranek and Newman, and elsewhere. The PDP-1 is the original hardware for one of the first video games, Steve Russell's 1962 game Spacewar!.

The PDP-8 is a family of 12-bit minicomputers that was produced by Digital Equipment Corporation (DEC). Launched in 1965, it was the first minicomputer to sell for under $20,000, and the $25,000 mark for a complete system would later be a defining characteristic of the minicomputer class. Over 50,000 units were sold during the model's lifetime.

The PDP-4 was the successor to the Digital Equipment Corporation's PDP-1.
