Well Murphy's Law has struck.
After selling my SX64 my C64 breadbin decided it's time to go on strike.
It's showing 30719 bytes free rather than the 38911. Although I get a cursor and can load stuff using the turbo chameleon it fails to run anything.
Discovered this when I decided to test my MMC Replay as it is no longer required (replaced with a version that works on the Vic20, 64, 16 and Plus4).
Any ideas what's wrong? I'm thinking maybe a ram chip failure?
