It *must* be used in an AT style machine? For several months I used my old
XT-style multifunction card with two 8250-based serial ports on it in my 
10MHz DTK AT clone, running both DOS and Microport UNIX on it. It worked 
fine, and I only swapped it for an AT-style serial board because I needed
the clock function of the XT board for an XT clone I assembled for a friend.
