IBM 5120 Computing System

Two years after launching the 5110, IBM introduced its 5120 Computer System in February 1980 as the lowest-priced IBM computer to date. A representative configuration — which included a main storage capacity of 32,768 characters of information, a 120 character-per-second printer and the BASIC programming language — could be purchased for less than $13,500. Overall system prices ranged from $9,340 to $23,990.

The 5120 Computer System featured the new desktop IBM 5110 Model 3 computer and two previously announced products: the IBM 5103 models 11 and 12 bidirectional, matrix printers; and the IBM 5114 diskette unit with up to 2.4 megabytes of direct access storage.
