|  Re: c16 64k cartridge problem solving
I would like to get a 64K cartridge working on my C16 REV.A without destroying pin 9 on the onboard memory. I have a https://www.pcbway.com/project/shareproject/OpenC16RamExpansion_V2.html cartridge by SukkoPera - which seems to almost identical to the coprolite cartridge memory-wise.
Does anyone know what non-destructive modification can be made to a Rev.A board to make the cartridge work? I would like to be able to unplug the cartridge, and have my C16 still work with 16K afterwards.
Alternatively, does anyone have schematics of the Rev.B? It would be interesting to compare it to the schematics of Rev.A to reverse engineer the changes they made in the hope of turning them into a modification for Rev.A.
