What does the Ampere’s WS-1 laptop and the Datsun 280Z sports car have in common? Both were designed by the same person: Kumeo Tamura. Technically, Tamura designed the case, which has an unusual clamshell design that resembles the wing of an airplane.
The case isn’t the only oddball part of the WS-1. Its 68000 CPU and VMEbus were unusual for a laptop at the time, and it featured an obscure multitasking operating system called BIG.DOS. Instead of bundling BASIC as the standard programming language, the WS-1 has APL.68000, a variant of APL. The machine was called the BIG.APL in early references. The system was sold in the U.S. through Work Space Computer of Torrance, California.

The IBM Portable PC was not IBM’s first portable. That was the Model 5100 from 1975 (if you want to call a 50-pound computer “portable”). It was launched in response to the Compaq Portable, which was similar in appearance and was introduced more than a year earlier. Compaq had made inroads into IBM’s customer base with the portable and IBM had no answer.
Essentially an IBM PC/XT in a suitcase-like form factor, the Portable PC made a few trade-offs versus the desktop model. Most obvious were a smaller screen and three fewer expansion slots than the PC/XT’s eight. You could buy an external monitor and an expansion unit to compensate, but then you would have spent more money than if you had bought the PC/XT.
Quite a few of the original IBM Portable PCs survive today. They were popular and well built.
