So this is my second favorite thing I got for Christmas this year. My Atari Punk Console is embedded in an Altoids tin, but I have seen them encased in most everything. Plug your amp into the 1/4” socket and enjoy the digitized noise. Two knobs control the sound. You can find a premade version on Etsy and Ebay. If your handy with a soldering iron you can find kits at a number of places (here’s one).
Atari 2600 videogames by manufacturer (part 2 of 2)
Sega, 20th Century (as in Fox), CBS (as in CBS) Activision, Spectravision Data Age, Coleco, homebrew
“Homebrew” refers to people coding their own games and then releasing them either in free ROM form (for emulators) or on cartridge (typically in recycled Atari cases) for sale. Edtris is reportedly the first homebrew produced after Atari itself stopped making games around 1990, and a good number more — many of which have been made into cartridge form — are now available.
