Welcome to the COSMAC ELF website, home of the TinyELF emulator, and a museum exhibit of sorts for computers based on the 1802 microprocessor.

1802 Documents

Enjoy this collection of documentation and old document scans, from 1802 technical data to microcomputer advertisements. We even have Tom Pittman's "A Short Course in Programming," the complete Ipso Facto newsletter archive, and Questdata newsletters.

Software Archive

New to the COSMAC ELF site, this software archive is small but will grow in the months ahead. We even have TMSI's version of Tom Pittman's Tiny BASIC now online!


Is it old technology or modern art? You decide. View pictures of 1802-based computers, then contribute your own!
