TOPS-20
Architecture: PDP-10


TOPS-20 is an operating system for the PDP-10, DECSYSTEM-20. It was descended from TENEX, an operating system for a modified version of the earlier KA10 PDP-10; hence its nickname of TWENEX.

Basic Use

Networking

TOPS-20 can work with DECnet and with TCP/IP. It was a popular machine on the Internet during its early days (1980s).

MIT added support for CHAOSnet.

Devices

How to get this running

TOPS-20 can run under emulation in SIMH, KLH10, and kx10.
