This is model 2140 from ak tronic, perhaps from around 1984. (As an aside, it seems some early C64 games were a bit minimal not because the programmers couldn't do more, but because they wanted to fit the games inside a 16K cartridge space.) I tried Gateway to Apshai 16K binary, but it won't run. Even if the device accepts 8K, 16K and 32K chips, it will only run 8K-sized chunks which rules out most games. Hold your horses, though, it won't run your freeze/fastload cartridge collection. It works as a 8-chip "carousel" cartridge EPROM switcher with the software-based selector menu burned in the 9th chip. I guess it can be seen as an alternative storage device. What is it? Truth be told, I'm not exactly sure what it is intended for.


The on-board chip appeared to be corrupt and only now I've had a chance to re-write the binary, which gave it life. This is an ancient device for the Commodore 64 I got a few years back.
