I've built something similar for a (c64) game development company about twenty-something years ago. On a normal day we would do numerous cartridge prototypes for testing etc - and going through UV-erase and EPROM-programming every time was just a waste of valuable time. Solution was that each developer got a development system that would mimic a cartridge - instead of eproms - it would be equipped with a ram circuit and a mechanism that could lock the ram for write access after performing upload of the cartridge image. An easy and quick way prototyping cartridges during development. /Uffe Message was sent through the cbm-hackers mailing listReceived on 2012-05-06 14:00:32
