The California Technologies International 1008-A uses for I/O storage a Micro Communications Corp. stringy floppy that pre-dates the Exatron Stringy Floppy drive used in TRS 80's. I have replaced the drive belt. Now when I attempt to load a wafer it appears to read the entire tape (while showing a "2" on the screen) and stops when done. I still can get nothing else out of this unit. It's possible that the entire thing is just an I/O device for another computer?
