Jim Brain is working on a new cartridge expander for the Commodore C64. The cartridges can be placed in 3 upright and 1 rear connector. Each cartridge slot can be controlled via 8 DIP switches (GAME, EXROM, IO1, IO2, ROML, ROMH, POWER). The proto-types are tested and the X-pander 3 will be for sale very soon, estimated price will be $30,--.
