chikiz Posted July 14, 2020 Share Posted July 14, 2020 So my friend has a Video Pinball cartridge with apparently a semiconductor testing mechanism(?) screwed into the cart itself (By checking its patents) with 2 joysticks. One of the patent numbers has no results for anything. Is this normal? Is this a test cartridge? I genuinely have no clue. Quote Link to comment Share on other sites More sharing options...
+bcombee Posted July 14, 2020 Share Posted July 14, 2020 This is likely a pirate cart. People would copy the ROM chips in Atari carts onto EPROMs and user these homebrew carts to play the backups. That lever mechanism is called a zero-insertion force socket and is used to hold the chips if place during use. 2 Quote Link to comment Share on other sites More sharing options...
