In May 1985, DEC (Digital Equipment Corporation) started the Prism project to develop RISC technology which would eventually replace their CISC -based VAX. Why would they do this? In the words of DEC's Gordon Bell, there is a major revolution in computer technology every then years and VAX first appeared between 1977-1978 http://h71000.www7.hp.com/openvms/30th/t_past_text.html#1985 Dave Cutler (working at DEC West in Seattle less than a mile away from Microsoft) headed Prism as well as software sub-projects named Mica, Emerald March 1988, DEC killed Prism so DEC could continue building larger VAX systems like Aquarius (now known as the failed VAX 9000). Later they would attempt to port VMS to new systems based upon RISC chips purchased from MIPS Summer 1988, Nathan Myhrvold heard about the demise of DEC West then introduced Bill Gates to Dave Cutler. Bill Gates wanted to build a better version of Windows which, at that time, was just a GUI overlay running on top of DOS. October 1988, Dave Cutler becomes a Microsoft employee and is put in charge of developing Windows-NT (new technology) which will run on multiple target platforms (initially: DEC-Alpha, MIPS, and Intel 386. Later inclusions: Intel 486, Intel Pentium). Dave takes most of his DEC West team with him to Microsoft. Incredible as it may seem, after the Prism/Emerald/Mica projects were shutdown, it seems that someone forgot to kill 64-bit RISC hardware development at DEC's facility in Hudson Massachusetts. This chip would later surface and be given the name DEC Alpha In 1992 DEC finished porting VMS from VAX to Alpha then renamed VMS to OpenVMS 6.0 Windows-NT 3.51 was popular and the GUI looked like Windows-3.1 and Windows-3.11 Windows-NT 4.0 was even better and looked like Windows-95 Windows-NT 5.0 was released as Windows-2000 and, at the time, was the most stable OS ever released by Microsoft Windows-2000 and portions of Windows-ME (millennial edition) merged to become Windows-XP (experience) A commercial version with SMP support was released called Windows 2003 Server Edition "VMS + 1 = WNT" makes no more sense than "IBM - 1 = HAL" (see HAL 9000) Bill Gates, who is known for not making mistakes in business, maintained two product lines at Microsoft which competed against each other (this gamble must have cost Microsoft a small fortune but the gamble paid off). Windows-95, Windows-98, and Windows-ME were designed by the Microsofties (original Microsoft employees) Windows-NT, the NTFS file system, Windows-2000, Windows-XP, and Windows Server Edition 2003, were designed by the DECies. The products designed by the DECies slowly took over the functionality of the Microsofty products as the two lines merged.
