Description

The RCA CDP1802 microprocessor (also known as "COSMAC") was the basis for several hobbyist computers in the mid 70s and early 80s. Join this group to discuss these old computers or share your 1802 experiences.

Visit cosmacelf.com for more on the history of 1802 microcomputing, data sheets, articles, photos, and more. You can find various emulators of ELF computers at elf-emulation.com (Unix/Windows), TinyELF.com (Mac OS X), and in the Files area of this group. There's even a simulator in Javascript that will run right in your browser.
