A memory expansion card by [[RAM7]].
This expansion allows to expand the CPC to a maximum of 2Mb 2Mbytes ram.
Possible configurations are: 256Kb256K, 512Kb512K, 1024Kb 1024K and 2048Kb2048K. Can use up to four SRAM chips (128K or 512K each), or alternately two SIMMs (256K or 1M each).
== Technical Specs. ==
Compatible with See [[Dk'tronics|dk'tronicsStandard Memory Expansions]] memory expansions Supported by [[FutureOS]] == Unknown Stuff ==
Unknown if the capacity is 256..2048 KbitUses Ports 7Fxxh, or 2567Exxh,7Dxxh,7Cxxh..2048Kbyte?Both doesnThat't make too much sense..s the same "extended standard" as used in CPC4MB.
* KBit would be nonsense (256Kbit would be only 32Kbyte).* Kbyte wouldn't be Dk'tronics compatible (which can handle max 512Kbyte)== Software that supports the RAM7 expansion ==
Possibly* [[FutureOS]]* And, it is 2Mbyteof course, and the first 512Kbyte 512K are accessed in Dksupported by all dk'tronics-style fashion, and the remaining 1.5MByte are accessed in unknown fashion?Dobbertin expansion compatible programs

* none?
