Actually, there were 4 different versions of the SuperCard hardware, 3 of them the plus version. There was the original 1541 "hair brush" style (pins sticking out of the bottom of it where it plugged into the 6502 socket), the cabled version where the brush style version was used with a cable (original 1571 option), and the direct cable connection to the board (no pins sticking out of it). I also made two revisions of the 1541 board, one with full sockets, and one with only the 6502 socket.
It looks like you have the very latest 1541 version I made. |
