It was released in February, 1984, and was eventually replaced by the IBM Convertible. The Portable was basically a PC motherboard, transplanted into a Compaq-style luggable case. The system featured 256 kibibytes of memory (expandable to 512 KiB), an added CGA card connected to an internal monochrome (amber) composite monitor, and one or two half-height 5.25" 360K floppy disk drives. Unlike the Compaq Portable, which used a dual-mode monitor and special display card, IBM used a stock CGA board and a composite monitor, which had lower resolution. It could however, display color if connected to an external monitor or television.Developer IBM 5155 Release date February 1984 Operating system IBM PC-DOS Version 2.10 (disk) CPU Intel 8088 @ 4.77MHz Storage capacity one or two half-height 5.25" 360K floppy disk drives Memory 256 kibibytes (expandable to 512 KiB) Display CGA card connected to an internal 9 inch monochrome (amber) composite monitor Graphics 80 X 25 text Weight 30 pounds This wasn't IBM's first <b>...</b>
