However, if the sound is completely different and distorted then there might be something wrong with your C128....
Is the metal case version and I've never heared a C64 (only emus) but the sound isn't normal
I've found these links:
C128 CHIPS AND COMMON SYMPTOMS
906112-02 (6581) early 128 SID: 12 volt VDD
318013-01 (8580) late 128 SID: 9 volt VDD
No sound (check also transistor Q2), weak or bad sound of one or more voices.
Is my SID chip fucked?
