Emulating (S)RAM with the Raspberry Pi Pico!

[@ninjazhu]

Any chance to test that on the cpc even if still 1k? It would be a step towards proving cpc can have hardware made in raspberry pi

Well, I think "tranditional RPi" and RPi Pico are quite different... this is, after all, more akin to a high-end Cortex-based microcontroller, not a SoC like the traditional RPi. So, your "original concept" doesn't quite apply ;-) But - I think it was already proved that the Pico is fast enough to provide, for example, CPC ROM Emulation. If ROM works, so should RAM, IMHO. However, the Microtronic here is *much slower* than the CPC, so timing is less critical. For the CPC, you'll need to overclock the Pico quite a bit AFAIK. My goal here is to turn this into a RAM-image based "mass storage" solution for the Microtronic, so that I can load and save RAM-Images from and to the Pico (via an EEPROM or SDcard). So SRAM emulation is only a means to an end for me here. Eventually, I'll also make this a banked memory expansion, add speech, and a display. Thanks for checking in, Zhulien!

... mach doch mal etwas langsamer - ich komme ja gar nicht mehr nach. 🤣🤣🤣🤣🤣😂😂😂😂 Dann warte ich mal auf die Github-Version
