I just got off the telephone with my computer guy and he said the old standard double density floppy disk should work in your keyboard. He said the 24-pin connector on your floppy drive is the same as the 34-pin connector, however, it only uses 24 of the pins. He said the connector is the same size and configuration.

He also suggested that you put out a feeler on ebay and you will likely find an exact duplicate for the one you are searching for.

Good Luck,

Gary
