CPC iRAM is a series of open source, DIY friendly, internal RAM expansions for the CPC 6128 and CPC 464/664 (later hopefully also for the 464 and 664Plus/GX4000).
The iRAM expansion sits in the CPU socket and requires no additional soldering inside the CPC.
* perfectly fits into a CPC 6128, even with socketed ROM or RAM. In Schneider CPC 6128 the metal shielding needs to be removed or altered.
Status: Finished, final PCB to will be tested. released in late 2025
=== CPC iRAM/1024 ===
* easy to assemble, all through-hole components
Status: first prototype PCB orderedFinished, not tested yetwill be released in late 2025
== paused = CPC iRAM/ 1024s === * much smaller than iRAM/1024, more similar in size to iRAM/640* for CPC 464 and 664* single 1MB SMD SRAM, upgrade to 1024K* [http://norecess.cpcscene.net/advancedmemoryusage.html C3 RAM banking] supported* easy to assemble, mostly through-hole components but one SMD SRAM Status: working prototype assembled, release unclear == considered == === PLUS iRAM/1024 === * 1Mb upgrade for Plus series * less DIY friendly, probably needs more complex CPLDs (ATF150x) Status: very early stage, still considering if it's feasible === GX iRAM/512 === * 512K upgrade for GX4000* less DIY friendly, probably needs more complex CPLDs (ATF150x) Status: just an idea == abandoned ==
