RE: C65 uses 6581 or 8580 ?

Hi Andre,

My board (missing VIC-III and CPU) came with 8580 chips. Given the date of
the machine, then this I guess would be the appropriate spec.

The 8580 runs on 9 V, the 6581 on 12 V.

Is fast mode available as an active high or low signal on the mother-
board? Then you could add a logic gate that keeps the SID chip select
high if fast mode is enabled.
