In 1981, IBM announced its first desktop computer, the System/23 Datamaster, just one month before the IBM PC.
A full-function data processing installation, with a single computer workstation and an 80 character-per-second printer, cost $9,830. At the time, that was IBM’s lowest-priced small business system. The cost of the word processing option ranged from $1,100 to $2,200.
