Anyone recall anything about the above? Specifically, I'm wondering if the expansion box and the card were the same for the LT and later FD/HD models. The LT tech ref shows expansion bus pin 60 as Gnd, whereas the info available for the FD/HD lists it as 'MOTOR ON'.
I'd note the FD/HD documents also show some of the logic reversed from the LT (ENABLE, TC, AEN and IOREADY), but I question whether they would be since the LT (image scanned) guide agrees to the ISA spec more closely.
