C64 screen flipping and faint audio

Post by syvix » Fri Jan 11, 2019 2:17 pm

Just picked up another C64 which had been modded with knobs for adjusting parameters in a audio cartridge (mssiah) and the screen constantly flips making it impossible to see/use. Also the audio coming out of all the audio ports is extremely faint. Cartridge works in my other C64 so its definately the computer. Not sure if any one had heard or had these problems before?
