The 924 used the same PC cards, same core planes, etc. It never had much commercial sale, but I believe it was used on some naval craft, possibly nuclear subs of the day. That machine must have come out about 1961 +/- two years. Harris Computer Systems grew out of the old Datacraft, whose machines were all 24 bits. Some contemporary Harris machines are still 24/48 bits (some 48 bit paths, some 24 bit registers and operations.)
