IBM Portable
Encyclopedia : I : IB : IBM : IBM Portable
The IBM Portable Personal Computer 5155 model 68 was an early portable computer developed by IBM after the success of Compaq's suitcase-size portable machine (the Compaq Portable). It was released in February, 1984, and was eventually replaced by the IBM Convertible.
The Portable was basically a PC/XT motherboard, transplanted into a Compaq-style luggable case. The system featured 256 kilobytes of memory (expandable to 640KB), an added CGA card and composite monitor, and 2 half-height 5.25" floppy disk drives. Unlike the design of the Compaq Portable, which used a very sharp double-scanning monitor and special CGA-compatible display card, IBM used a stock CGA board and a composite monitor, which was not as sharp.
