Developer cartridge which uses EPROM chips to hold binaries of (non-final) game code. Those cartridges were using during software development.
They could hold either 2 4MBit or 8 MBit chips, so 8 or 16 MBit in total. The cart also has 32 KByte of SRAM for saving, while standard carts only have 8 KByte.
4 DIP switches on the cartridge let you select which size of EPROM chips is used and if the SRAM is to be used:
- DIP 1: EPROM size
OFF: 4 MBit EPROMs, ON: 8 MBit EPROMs - DIP 2: not used
- DIP 3: SRAM
OFF: Don’t use SRAM, ON: Use SRAM - DIP 4: not used
