Description
4 MB DRAM internal memory expansion for CPC.
- Its first 512 Kbyte are compatible with external memory expansions (Dk'tronics, Inicron RAM expansion, SYMBiFACE II etc.), using port #7Fxx (see Standard Memory Expansions).
- Its first 2 MB are compatible to RAM7's 2 MB expansion.
- The whole 4 MB can be used trough ports #78xx to #7Fxx (see CPC4MB Page, for futher details).
Software
- Currently, CPC4MB is supported by FutureOS version .8.
- The 4 MB E-RAM Test: Media:4_MB_E-RAM_Test.zip
- The first MB of the 4 MB expansion (&7Fxx, &7Exx) is supported by SymbOS version 2, but buggy.
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.
