Ahem. So maybe the repairman who claimed to have replaced my SID actually
did so (I compared the motherboard with a circuit diagram from a magazine,
and according to that one, the replaced chip was the PLA next to the SID).
Since that particular C64 is dead, maybe I should open it and check the
chip numbers to identify what chip actually was changed.
(but the problem, a "buzzing" sound, was not within the computer but a
faulty power supply which the shop personal kindly informed me about
after paying for the unneccessary repair job ;-)
