Columbia Data Products (CDP) was a company which produced some of the first IBM PC clones. It faltered in that market after only a few years, and later reinvented itself as a software development company.

Columbia Data Products was founded in 1976 in Columbia, Maryland.
Publicly listed PC-clone makerEdit
CDP introduced the MPC 1600 "Multi Personal Computer," designed by David Howse, in June 1982. It was an exact functional copy of the IBM PC model 5150 except for the BIOS which was clean roomed. IBM had published the bus and BIOS specifications, wrongly assuming that this would be enough to encourage the add-on market but not enough to facilitate unlicensed copying of the design.
CDP advertisements stated that the MPC "can use software and hardware originally intended for the IBM Personal Computer". The "Multi" in its name hinted to the fact that it could also run the multi-user operating system MP/M-86. The MPC was the first IBM PC clone and was actually superior to the IBM original. It came with 128 KiB RAM standard, compared to the IBM's 64 KiB maximum. The MPC had eight PC expansion slots, with one filled by its video card. Its floppy disk drive interface was built into the motherboard. The IBM PC, in contrast, had only five expansion slots, with the video card and floppy disk controller taking two of them. The MPC also included two floppy disk drives, one parallel and two serial ports, which were all optional on the original IBM PC. The MPC was followed up with a portable PC, the 32 pound (15 kg) "luggable" Columbia VP in 1983.
In May 1983, Future Computing ranked Columbia and Compaq computers as "Best" in the category of "Operationally Compatible", its highest tier of PC compatibility. PC Magazine in June 1983 criticized the MPC's documentation, but reported that it had very good hardware and software compatibility with the IBM PC. BYTE in November 1984 approved of the portable MPC-VP's PC compatibility, reporting that it ran Microsoft Flight Simulator, WordStar, Lotus 1-2-3, dBASE II, and other popular applications without problems. It concluded that the computer was "one of the best overall bargains on the market today".

In February 1984 IBM announced the introduction of their first portable PC, thus putting pressure on its competitors in this niche a well, which besides CDP already included Compaq as the market leader in this segment, as well as Kaypro, TeleVideo Corporation, and Eagle Computer.
Columbia also released upgraded desktop models in order to compete with IBM PC XT. Their MPC 1600-4, briefly reviewed in PC Magazine of April 1984, was found a worthy competitor of the XT and without major compatibility problems, even though its hard drive controller was quite different from IBM XT's, being based on a Z80 microprocessor with 64 KB of RAM emulating the ASIC used by IBM.
The competition in the PC market became more intense in June–July 1984 with several companies, including IBM, announcing price cuts, and with AT&T entering the PC market as well. Besides CDP, other PC clone companies like Eagle were also having a hard time as a result. Discussing the perspectives of the smaller PC firms like CDP, Eagle, or Corona Data Systems, one Morgan Stanley analyst was quoted in the June 9, 1984 issue of the New York Times saying "Some of them are operating at 5 percent pretax margins, and there is just no room for more price cuts." By August 1984 the CDP sales were faltering and CDP announced layoffs of 114 employees at its Maryland headquarters and 189 employees at a second factory in Puerto Rico. By April 1985 their stock had dropped to US$0.50 and was delisted. The company filed for Chapter 11 protection in May 1985.
The company was taken private in 1986 and continues to operate under that name.
In 1987 CDP shifted emphasis from hardware to software. They developed and licensed Small Computer System Interface (SCSI) software to Western Digital (WD), a supplier of hard drive controllers. In 1991, WD sold their SCSI business to Future Domain, where it languished.

Columbia Data Products (301-992- 3400) turns out another split-personality computer, appropriately named the Multi-Personal Computer. Using only the Intel 8088 microprocessor, it manifests its duality in an ability to run both I.B.M.-oriented software and software requiring an operating system called MP/M-86.
