3Server
The 3Com 3Server was a headless dedicated network-attached storage machine designed to run 3Com local area network (LAN) server software, 3+Share. Background The companion product was the diskless 3Station network workstation, a dedicated client machine. However, 3Servers could also network with standard PC-compatibles and were commonly used in this role. Having no display other than a small one-line LCD and no keyboard or mouse interface, 3Servers were controlled via another PC on the network which allowed console access to the internal server software. The original 3Server was a x86 computer that wasn't compatible with any ordinary PC based on an Intel 80186 CPU, running a special version of MS-DOS and 3Com's proprietary 3+Share network server software. This was a multitasking network server stack that ran on top of single-tasking DOS. Internally, it had a network stack, file and print server modules, disk caching, user handling and more, all running simultaneously inside t ...

3Station
The 3Station was a diskless workstation, developed by Bob Metcalfe at 3Com and first available in 1986. The 3Station/2E had a 10 MHz 80286 processor, 1 megabyte of RAM (expandable to ), VGA-compatible graphics with of video RAM, and integrated AUI/10BASE2 ( BNC) network transceivers for LAN access. The product used a single printed-circuit board with four custom ASICs. It had neither a floppy disk drive nor a hard disk nor any cooling fan device, and thus it was 100% silent during operation, booting from a special "Startvolume" - (SW-Image) located at the preferred 3server-XXX Server, while also loading / storing all (HW/SW) Drivers, end-user Apps & Data files on a preferred 3Com Network Server. Because of its very straightforward, simple and optimized internal HW and SW architecture, the 3Station/2E Nnetworking PC appeared to operate extremely fast and efficient during the daily workload for the actual Network Client. The 3Station/2E HW (Systemboard etc.) was further embedded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3+Share
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9 ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the early 1960s. The company produced a series of machines known as the Programmed Data Processor, PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space.

OS/2
OS/2 is a Proprietary software, proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, intended as a replacement for DOS. The first version was released in 1987. A feud between the two companies beginning in 1990 led to Microsoft’s leaving development solely to IBM, which continued development on its own. OS/2 Warp 4 in 1996 was the last major upgrade, after which IBM slowly halted the product as it failed to compete against Microsoft's Microsoft Windows, Windows; updated versions of OS/2 were released by IBM until 2001. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "IBM Personal System/2, Personal System/2 (PS/2)" line of second-generation PCs.
