It returned 255. After I did that the TV screen went fuzzy and turned black. I tried to reboot the machine and the floppy drive once again has stopped working. I wonder what is wrong with the machine. I'm certainly curious. Before typing the command it seemed to be okay aside from the floppy drive.
I'll try reseating some chips, although I didn't get to doing that previously before it "fixed" itself. Maybe I'll focus on the disk drive... if the IIc boots again that is.
Thanks for your help, I'd love to play around with this machine and use the Joystick and Ms. Pac-Man disk I got working with my IIgs. Update:
I took out and placed back in all the removable chips and the system booted normally, still the disk drive acts up. I'll try to open that next, however it doesn't seem to have any "fixable" bits that can fall off, besides the cable.Update 2:
Opened the disk drive, reconnected cables and re-tightend screws, no change. Oh well... maybe getting the new ROM will let the IIc work with my IIGS external drive? Or no?

for an enhanced chip says "Not sure" (Under questions section.)
I think I have a 3.5 disk drive... maybe I'll see if that will work.
