Commodore IEEE-488 Interface adapter - C64 & C128 to IEEE-488 Devices c64_ieee488

Commodore 64 IEC64 IEEE-488 Interface Board (IEC64W)

This card was very handy if you had the Commodore SFD-1001 floppy, which had only one IEEE-488 connector. But also the old CBM floppy drives which could be connected to a C64 or C128.
