Compaq Computer Corp. (Houston, Tex.)

Founded in February 1982, Compaq had over $111 million in sales in 1983, making it the most successful first year for any company up to that point. It did so on the strength of its Compaq Portable and Compaq Plus models.

Compaq’s Portable put the company on the PC map, and the Portable series was by far the most successful luggable PC design. Compaq shipped more than 28,000 Portables in the first nine months of 1983 alone. Damaged cases, non-working drives, and faulty displays are common ailments in systems found today. Be careful taking Portables and Pluses apart. The case is held in place by tabs on the sides that snap into the chassis. You need to find these tabs and press to release them.

In 1985, Compaq introduced the TeleCompaq, a modified Portable design for use in telephone communications. It had a separate Z80 processor for communications tasks and a phone handset. Compaq thought enough of the TeleCompaq’s potential to form a subsidiary to market it and other communications products, but it was short-lived and an uncommon find today.

The PC AT-compatible version of the Portable was a good seller for Compaq, at least until the Portable II became available. The Portable II was smaller, improved version of the PC AT-class Portable 286.

A change of form factor came with the Portable III. The so-called sewing machine format was replaced by the smaller “lunchbox” shape. The Portable III came in three versions. The Model 1 had a single floppy drive, and the Model 20 and Model 40 had 20MB and 40MB hard drives, respectively. The Portable 386 used similar model designations, but offered a 100MB Model 100 and no 20MB model.

The Deskpro was Compaq’s first desktop computer, and it soon established itself as one of the best made and most IBM-compatible PCs on the market. Many Deskpros saw years of business use, and examples in excellent condition are unusual. The PC AT-compatible Deskpro 286 appealed to power users in part because of its expandability. It could accommodate up to 8.2MB RAM by using expansion boards. The Deskpro 286 model was upgraded to a 12MHz 80286 in early 1987. The new model also had faster memory and more mass storage options.

The Deskpro 386 was one of the first 386 systems, and it was a hot seller. In September 1987, Compaq introduced the Deskpro 386/20 with a 20MHz 80386 CPU. The 386/20 incorporated Compaq’s then-new Flex Architecture, which featured improved memory caching and a combined memory and I/O bus. Compaq assigned Deskpro model numbers according to the size of the hard drive.
