The Compaq Portable III – 1987
The Compaq Portable III was released in 1987 for $5K including a 20 MB hard drive. Weighing in at around 20lb, the IBM PC clone was very successful. No batteries were included – like most lunchbox computers, it’s really a transportable desktop, and needs to plug in to an external power source. Compaq became a very large PC manufacturer very quickly (with both desktop and portable offerings) and in 1988 had sales of $1.2B
Initially offered with an Intel 80286 processor, the Compaq Portable II really became useful when the 20MHz 386 processor version came out.
640K of RAM was standard
Gas plasma 10″ display – 640 x 400 (80 x 25 text) – I think this is CGA
Expansion slots were only available through an add-on module, which was a bit ungainly and from memory, not 100% reliable.
Ports: Serial, parallel, Video RGB and a connector for the expansion box
Size 41 (W) x 19.2 (D) x 24.8 (H) cm / 11 kg
