This summer, my plan was to clean up my old Apple IIGS and transfer some floppy disks to a PC with ADTPro.
I've plugged-in everything, I've put a 3.5 inch disk in the drive, powered-on and it did boot well, after 25 years of hibernation. The demo that I was launching confirmed to me that the IIGS was working perfectly.
Alas, when I set the control panel to boot on slot 6 drive 1, where the Disk II 5'1/4 drive is connected to a controller card, nothing happens. The reader does not calibrate, the LED does not light up, nothing inside the drive is moving.
I can't see any fried chip on the contrller or on the top PCB in the drive (I have not taken it appart yet). I've tried the simplest things, like unplugging / re-plugging the controller board and every cable (carefully marking initial positions). I've pressed (gently) on all the PROMs and chips, to no avail.
If anyone has any ideas on how to proceed from there, I'm interested. :)
