Pictured above is a standard Jaguar EPROM cartridge. This cartridge uses four 27C020 (I believe) EPROMs. But unfortunately, to use this on a production model Jaguar (non-development) the program needs to be encrypted. There's been word that you can use a download cartridge to partially encrypt the program, then take the flash ROMs out of the download cartridge, read them in a EPROM reader, then burn the program onto EPROMs and it will work! There's also a two EPROM socket version that uses EPROMs that are 16bit wide. If you would like to obtain one of these boards, contact:
