The 1771 is a
single density only controller and not suitable for use with
3.5" disks. You want a board with a 765 (compupro) or 1793 CCS and a raft
of others.
OK. I'll go 5 1/4". Can you clue me in on how it works?
Just like the 1793 in dingle density mode.
Anything more than that is 20 pages of close spaced text. Look around for
an old book or another board with 1771 and DOCs!
