Having cleaned the heads, about every other disk going
through a box of
8" 820 disk, sthere is nothing in the drive other than the drives and a
power supply. I am not sure if the 820-II is different but, I doubt it.
The cable just splits off to each drive. Everything is on the mainboard.
My 82O-II does indeed have its floppy controller on a daughterboard. I
suspect this is a different arrangement from the original 820 aka Ferguson
Bigboard.
