Transistorized computers

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.

BESM (БЭСМ) is the series of Soviet mainframe computers built in 1950–60s. The name is an acronym for "Bolshaya (or Bystrodeystvuyushchaya) Elektronno-schotnaya Mashina" ("Большая электронно-счётная машина" or "Быстродействующая электронно-счётная машина"), meaning "Big Electronic Computing Machine" or "High-Speed Electronic Computing Machine". It was designed at the Institute of Precision Mechanics and Computer Engineering

The PDP-6, short for Programmed Data Processor model 6, is a computer developed by Digital Equipment Corporation (DEC) during 1963 and first delivered in the summer of 1964. It was an expansion of DEC's existing 18-bit systems to use a 36-bit data word, which was at that time a common word size for large machines like IBM mainframes. The system was constructed using the same germanium individual transistor-based System Module layout as DEC's earlier machines, like the PDP-1 and PDP-4.

The PDP-9, the fourth of the five 18-bit minicomputers produced by Digital Equipment Corporation, was introduced in 1966. A total of 445 PDP-9 systems were produced, of which 40 were the compact, low-cost PDP-9/L units.

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