He certainly meant a 1542. You won't get luck with that thing. Doesn't
use bus-master DMA, a half-hearted solution with respect to multiprocessing
systems. I've got experience with a 1542B and a 1540A (the *40 are w/o
floppy ctrlr). Both work fine, the 1542C has h/w problems since it's
able to run SCSI/2 and thus has much tighter timing conditions, that
*might* cause trouble with bad cables. (Flat cables as used inside the
boxes are always okay.)
Some other controllers have been reported to be okay.
