RAM7 2MB memory expansion: Difference between revisions

Latest revision as of 13:43, 28 October 2023

A memory expansion card by RAM7.

This expansion allows to expand the CPC to a maximum of 2Mbytes ram.

Possible configurations are: 256K, 512K, 1024K and 2048K.

Can use up to four SRAM chips (128K or 512K each), or alternately two SIMMs (256K or 1M each).

Uses Ports 7Fxxh,7Exxh,7Dxxh,7Cxxh. That's the same "extended standard" as used in CPC4MB.

FutureOS
And, of course, the first 512K are supported by all dk'tronics and Dobbertin expansion compatible programs

-Compatible with [[Dk'tronics|dk'tronics]] memory expansions

-Supported by [[FutureOS]]
-== Unknown Stuff ==
-Unknown if the capacity is 256..2048 Kbit, or 256..2048Kbyte?

-Both doesn't make too much sense...
-* KBit would be nonsense (256Kbit would be only 32Kbyte).
+== Software that supports the RAM7 expansion ==
-* Kbyte wouldn't be Dk'tronics compatible (which can handle max 512Kbyte)
-Possibly, it is 2Mbyte, and the first 512Kbyte are accessed in Dk'tronics-style fashion, and the remaining 1.5MByte are accessed in unknown fashion?
+* [[FutureOS]]
+* And, of course, the first 512K are supported by all dk'tronics and Dobbertin expansion compatible programs
 == Weblinks ==
+* none?
