Purchased for amber CRT to swap into SE/30. Hard drive spins up but eventually slowly blinks red LED Inside has a CGA video card, a universal floppy controller, a hard drive controller, and an AST SixPackPlus memory card.

The IBM 5155 helped bring the IBM PC platform into the “luggable” era, packaging PC-compatible computing, a built-in monitor, and expansion capability into a transportable suitcase-style machine in 1984. It matters less as a true portable by modern standards than as a sign of how quickly business computing was becoming mobile, and as IBM’s answer to the success of machines like the Compaq Portable. Of particular note with respect to vintage apple collectors, the CRT in it is compatible with the compact Macs, such as the SE and SE/30.
