Ah, so there is probably lots of gating inside the GAL ;-) In my opinion the SID belongs to the C64 anyway and I don't care much about alternative uses like the Plus/4, the SIDstation and the HardSID. I even find it _extremely_ strange that CBM used in the B series! But, how much is such a Plus/4 SID cart and does it come with or without SID? > Finally, I found a more obvious example that could be examined easier. > This is the interface plug of the 1551 floppy drive.

The only one I ever saw belonged to a friend, but I think she stopped using her Plus/4 setup when I sold her a C64 with 1541 and Speeddos. Unfortunately both setups dissapeared in a very sad way, and we all don't really want to know the details. Nicolas - This message was sent through the cbm-hackers mailing list.
