That must have been one of the last drives manufactured by Jasmine. Note that the mechanism is a MiniScribe and looks like it was the original equipment.

From March 1989, Jasmine and Rodime (their disk OEM) were at legal war which contributed to the demise of both companies. My understanding is that Jasmine folded in early 1990 before they shipped the DirectServe (a truly interesting AppleShare server) in significant numbers.

The original DirectDrive (strike DirectServe) drive was not mains powered and drew power from the floppy connector. Does anyone know when Jasmine first shipped conventional SCSI drives?
