2026-03-12: Cocopedia.com is now using a new caching system that should make things faster. Please let me know if you encounter any new issues. 2026-03-15: MediaWiki has been reinstalled and the old database and files restored. It was pretty clogged up from being upgraded so many times since 2004. I am also testing out Cloudflare to see if it can prevent the 'bot assaults that took the site down last year. 2026-03-16: Special thanks to Don Barber for hosting a backup mirror of CoCopedia: https://cocopedia.dgb3.net

Home / Hardware - GIME

GIME is/was a custom ASIC chip used in the Color Computer 3. It was designed by VLSI.

Known Versions

PCB Prototypes - Implemented in discreet logic on the large PCB prototype units. Microware was known to have had at least two of these units, which today are in the collection of User:AllenHuffman.
Pre-Production - Launch-title developers received early production run CoCo 3s that had pre-production GIME chips. At least two variations are known to exist. We need to catalog and document them here.
1986 - Code named "Tequila". This was the original production GIME. It contained some bugs that were fixed in a second revision.
1087 - Code named "Tortilla".
