Description
4 MB DRAM internal memory expansion for CPC.
- It's first 512Kbyte are compatible with external memory expansions (Dk'tronics, Inicron RAM-BOX), using port #7Fxx (see Standard Memory Expansions).
- Additional 3.5MBbyte can be used trough ports #78xx to #7Exx (see CPC4MB Page, for futher details).
Software
- Currently, CPC4MB is supported by FutureOS version .8.
- The first MB of the 4 MB expansion (&7Fxx, &7Exx) is supported by SymbOS version 2.
Schematics
Altrough CPC4MB can be ordered fully asembled (even with mounting on a CPC board), there's still a download of PCB design on CPC4MB page, if you want to DIY.
