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 MB 5.25" floppy, and a 10" amber colored gas-plasma display. Other models included the Model 20 at 4999 USD which added a 20 MB hard disk, or 5799 USD for the Model 40 with the upgraded 40 MB hard disk.
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 USD. Power is supplied using a mains electricity outlet; no battery exists.
