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.
