# PDP-10 Simulator Configuration

The PDP-10, also known as the DECsystem-10 and the DECsystem-20, was among the most famous and popular 36-bit computers. Digital introduced its first 36-bit computer, the PDP-6, in 1964. The product was not a success. Digital relaunched the family, with a new design, as the PDP-10 in 1966, and shipped the first systems in 1967. In all, Digital brought six 36-bit designs to market:

- 1964: PDP-6 - first design
- 1967: KA10 - first PDP-10
- 1972: KI10 - first DECSYSTEM-10
- 1975: KL10 - first ECL design - as DECSYSTEM-10, as DECSYSTEM-20
- 1978: KL10B - extended addressing KL10
- 1979: KS10 - last 36-bit system, also known as DECSYSTEM-2020
