Compaq Deskpro 386s

I have a vintage Compaq Deskpro 386s (386SX @16MHz from 1988-1990) with a smashed HDD and failed CMOS battery. I managed to get another battery and to get the SP0308 floppy disk required to configure the CMOS data (these machines have no built-in BIOS setup).

Compaq Deskpro 386s Compaq was a bold and innovative company, producing some of the best computers of the 1980s. Founded by trio of former Texas Instrument employees, the company famously (and legally) reverse-engineered the IBM PC and created the first successful portable PC. After making a name for itself, Compaq pivoted to the desktop.

The Compaq Deskpro was a line of business-oriented personal computers manufactured by Compaq, then discontinued after the merger with Hewlett-Packard.[1] Models were produced containing microprocessors from the 8086 up to the x86-based Intel Pentium 4.[2]

The original Compaq Deskpro (released in 1984), available in several disk configurations, was an XT-class PC equipped with an 8 MHz 8086 CPU and Compaq's unique display hardware that combined Color Graphics Adapter graphics with high resolution Monochrome Display Adapter text. As a result, it was both considerably faster than the IBM PC and had a much better quality text display compared to an IBM PC equipped with graphics.[1] Like the earlier Compaq Portable, its hardware and BIOS were 100% compatible with the IBM PC Model 5150 (a characteristic that few other PC workalikes shared so soon after the establishment of the IBM standard).

In 1985, Compaq released the Deskpro 286, which looks quite similar to the IBM PC/AT. Then in September 1986, the Deskpro 386 was launched[3] after Intel released its 80386 microprocessor, beating IBM by 7 months on their comparable 386 computer, and thus making a name for themselves.[4]PC Tech Journal honored the Deskpro 386 with its 1986 Product of the Year award.[5] The Deskpro 386/25 was released August 28, 1989 and cost $7,999.[6]

The form factor for the Compaq Deskpro is mostly the desktop model which lies upon a desk, with a monitor placed on top of it. Compaq has produced many tower upright models that have been highly successful in sales, and are usually convertible to a desktop form factor. An SFF (small form factor) desktop version was also produced during the Deskpro's lifetime. The Deskpro was replaced by the Evo in 2001.

The many different models include the:

  • Deskpro 286e
  • Deskpro 386 released as the first MS-DOS, PC-compatible 32-bit computer with 386 processor.
  • Deskpro 386S (Second Generation 386 introducing 16-bit bus 386SX processors)
  • Deskpro XE 486 ISA and IDE
  • Deskpro XL High-End workstation with EISA and SCSI either and 486, Pentium, Pentium Pro
  • Deskpro M 386, 486 and 586 early Pentium models
  • Deskpro 2000 Pentium 1, Pentium Pro and Pentium 2
  • Deskpro 4000 Pentium 1 with MMX & Pentium 2
  • Deskpro 6000 Pentium 1, Pentium Pro and Pentium 2 and scsi
  • Deskpro DX
  • Deskpro EXD, SB , EN , ENL: Pentium III based
  • Deskpro EVO500 series, the last of the range with Pentium 4 processors

Compaq Computer Corporation was a company founded in 1982, that developed, sold and supported computers and related products and services. Compaq produced some of the first IBM PC compatible computers, being the first company to legally reverse-engineer IBM Personal Computer. It rose to become the largest supplier of PC systems during the 1990s before being overtaken by Dell in 2001. Struggling in the aftermath of the dot-com bubble bust, Compaq was acquired for US$25 billion by HP in 2002. The Compaq brand remained used by HP for lower-end systems.
On June 28, 1984 Compaq released the Compaq Deskpro, a 16-bit desktop computer using an Intel 8086 microprocessor running at 7.14 MHz. It was considerably faster than an IBM PC and was, like the Compaq Portable, also capable of running IBM software. It was Compaq's first non-portable computer and began the Compaq Deskpro line of computers.
Our model is from Series 3021 with 256VGA.
The srial number is 8204HBW 31815 and the keyboard has a part number of 109232
