The Personal System/2 Model 50 is a midrange desktop computer in IBM's Personal System/2 (PS/2) family of personal computers. First released in April 1987, the Model 50 features an Intel 80286 processor running at a clock speed of 10 MHz. In June 1988, the PS/2 Model 50 received an update in the form of the Personal System/2 Model 50 Z, which offered faster RAM, eliminating the insertion of wait states endemic to the original Model 50 and increasing system performance. The Model 50 was the best-selling line of PS/2 for several years, IBM selling over 440,000 units in the first year of its availability.
