I need the Floppy Drive, as that's the only way to reinstall the system software after having a bubble/cmos memory replacement.
However I have a chance to hold a Okuma Floppy Drive and took some photo on it.
I did tried to replace the original floppy drive with off-the-shelf PC floppy drive. As the circuit board consist of simple components and layout. I also notice that the different of floppy drive is just the jumpers next to the input power socket.
Any suggestion if I want to build another unit of this?
