IBM Personal Computer Model 5100 (1975)

IBM Microcomputer Model 5100

The IBM 5100 Portable Computer weighed about 50 pounds, had a built-in tape drive, a small CRT, and could run programs in BASIC or APL. The PC relied on IBM's own circuit modules, and did not use an Intel microprocessor. The tape drive used a inch tape cartridge that could store about 200K of data. The cost of the system was about $10,000. It was not successful in the marketplace. It was not until IBM released the IBM PC in 1981, that IBM became a powerful player in the PC world.
