About Tequestafarian

Old machines. New ideas.

Tequestafarian is where I document the games, communications tools, ANSI projects, and other retro-computing experiments I build for the Tandy Color Computer 3 and related vintage systems.

I still like using old computers, so I make stuff that gives me more reasons to turn them on. Sometimes that is a game. Sometimes it is a terminal or a networking tool.

Nothing here is ever really finished. These are hobby projects, and I expect all of them to keep changing as I use them, find bugs, and get new ideas.
