You can use the codes for the 8050/8250, since the DOS ROM is the same for
all these drives. If you look here:
http://www.funet.fi/pub/cbm/schematics/drives/old/8050/8050-05.gif
you can see that five flashes are a zeropage fault, and the cause can be a
bad 6530 or 6502. From experience, it's the 6530. It's the 40 pin chip that
sits on the small daughterboard. It might be worth to check if the
daughterboard is connected well, because that might be another reason for the
blink code.
