Bryce finished another hardware project, this time for the Amstrad Plus series. It is a multi cartridge, which contains a 512 KB EPROM or Flash-ROM on which you can place 4 128 KB ROMs. You can use the DIP switches on the cartridge to select which of the four ROMs shall be used by the CPC. As always you can find more information about the cartridge and the board layout in the Multi Cartridge article in the CPC Wiki. The project can be discussed here.
NOTE: You will still need a ACID protection chip in this cartridge.
