the only thing i have to offer is that i did notice when using the Apple® 800k floppy drive with the Macintosh 128k.
it works. @ as 400k drive.
but if i install that same 800k floppy drive internally i have to make sure to use a special cable that has pin 9 and pin 20 cut.. then the drive works. or else it will try to burn out the eject motor.
So the bridge board in the Apple® 3.5 800k external must also disable pin 9 and 20 as well. I don't know if that helps anything… lol
