1982- Compaq Portable I (3/2024)Tags
CompaqDescription
Announced November 1982, the unit was actually shipped in January of 1983 (300 of them). This was arguably the system that destroyed IBM's monopoly on the PC market and created the situation we see today. It WAS the first compatible system that was LEGALLY made, though Columbia first copied the IBM BIOS and later paid the fatal price. The system's BIOS was developed from scratch by using a team of 18 persons (only one guy was "dirty" and he was not allowed to do any part of the code and could only answer vaguely to questions). They took IBM's BIOS apart and made notes of the system calls contained within it. That way, Compaq was able to develop a PC compatible without any risk of a lawsuit from IBM, since the code was written from scratch (reverse engineering). It cost them $1 million to do it. The system itself weighs a hefty 34 pounds and was dubbed a 'luggable' computer rather than a true portable. It contained a 9" green phosphor CRT display and both serial and parallel ports. The system did MDA graphics as well as CGA by switching the scan frequencies of the monitor (a first that is the basis for VGA).
The only difference between the standard and 'Plus' models was that the latter had a single 5.25" floppy drive and a 10Mb hard disk, while the original model had two 5.25" drives. All units supported two 5.25'' floppies at 160 KB, 320 KB and 360 KB. All units could have 10, 20, or 30 MB hard drives but Compaq only shipped 10MB Rhodime ruggedized drives (good for 40 G shock!). Some models also had a 20/40 MB tape drive. Compaq also shipped a brown nylon or brown leather carrying case and ONE blue case (Rod Canions unit).
In its first year of trading, Compaq took more than $111 million on this single product, which was a US business record. During that year (1983), more than 53,000 units were sold.
