All fused separately. (12V isn't needed for the C64, but I also have a 1541-II). > > any way to produce the 9vac from DC ? > there is the problem of galvanic isolation... yes there's a way, but I think you need an inverter-like electronics with a transformer to float the 9V ac with respect to the +5V ground.
