Check the listing for details. PCB 2 CHIP CARTRIDGE for Atari Jaguar PROTOTYPE/TESTING. Listed at 24.95 USD. Jaguar Cartridges 2 Chip PCB with Sockets(42 pin DIP) and 93C46 SRAM. These boards are made to use 8 meg or 16 meg 16 bit EPROMs such as the 27C800 or 27C160. These are for Demo, Prototyping and testing. Because these have sockets they will not fit in standard Atari Jaguar Cartridge cases The covers will not accommodate a chip in a socket. We also sell these boards bare without sockets, capacitors and SRAM that will fit into the standard Atari Jaguar cartridge shells when the chips are soldered in(not socket-ed).
