Are you suggesting that IBM has produced over 10,000 different computer
models? I doubt it!
The IBM 5120 I'm (only slightly) familiar with is
a later version of the
IBM 5100 portable computer from 1975.
Does anybody know all the machines that comprised the 51xx series? The
few I know are:
5100, IBM Portable
5110, similar with optional (?) 8" flops
5120, bigger screen, built-in 8" flops
5140, Convertible
5150, PC
5155, Portable PC
5160, PC/XT
5180, PC/AT
Was there a 5130?
