The Compaq Portable III is a PC/AT-compatible computer released by Compaq Computer Corporation in 1987. It was advertised as being much smaller and lighter than the previous portable x86-PCs; however it was still quite large by today's standards. Three models were announced at release. The Model 1 had a list price of $3999 USD and was equipped with a 12 MHz Intel 80286, 640 KB RAM, 1.2 megabyte 5.25" floppy, and a 10" amber colored gas-plasma display. Other models included the Model 20 at $4999 USD which added a twenty megabyte hard disk}}, or $5799 for the Model 40 with the upgraded forty megabyte hard disk.
When Compaq launched its Portable III, the launch was timed to occurs simultaneously in twelve countries around the world, in keeping with Compaq's showmanship style. The Portable III was designed to be the smallest, lightest and fastest 386 machine, since Compaq was under the pressure from Toshiba with it's T-1100 and T-3100 and Zenith with it's Z-181. Compaq only had 286 motherboards ready mass production, so the 386 version, the Compaq Portable 386, would follow about one year later.
The design of the Portable III had been deeply modified over the earlier Compaq portable series of machines. It was half the size and its footprint occupied half the space of the first Compaq Portable. The most remarkable feature was its gas plasma display which lifted up and swiveled so that it could be placed in a good position for reading. It also has a proprietary graphics mode that allows it to run at true 640 x 400 mode. Windows 2.11 had a Compaq Portable display driver for 640 x 400 mode, but Windows 3, and later Microsoft operating systems require the memory management of Intel 386 CPU. The Portable III lacked the internal expansion ports of previous Portables and desktop PCs of the time, but Compaq offered an optional external expansion unit(model 2662A), that provided two full length, 16-bit ISA add-in cards for $199. Power is supplied using a mains electricity outlet, it was not designed to run on batteries.
