This article is about the rebuild of an old IEEE-488 interface card for the Commodore C64 and Commodore C128. This card was very useful if you had e.g. the Commodore SFD-1001 floppy which had only one IEEE-488 connector. But also the old CBM floppy drives could be connected to a C64 or C128. Since such hardware is getting rare and hard to get, I rebuilt the board.
