The BT Merlin M4000 was a Personal computer sold by British Telecom during the 1980s as part of the Merlin range of electronic machinery for businesses.
 It was not developed by BT but was a rebadged Logica VTS-2400 Kennet, and a completely different machine from the Merlin Tonto which was a rebadged ICL OPD.
 Merlin M4000 was designed as a general purpose computer but was not IBM PC compatible, and so could not run the major business applications around at the time as these were tied to the IBM PC hardware.
The ChessMachine was a chess computer sold between 1991 and 1995 by TASC (The Advanced Software Company).
 It was unique at the time for incorporating both an ARM2 coprocessor for the chess engine on an ISA card which plugged into an IBM PC and a software interface running on the PC to display a chess board and control the engine.
 The ISA card was sold with a CPU running at either 16 MHz or 32 MHz, and 128 KB, 512 KB, or 1 MB of onboard memory for transposition tables.
 This made economic sense at the time of introduction because mainstream PCs were only running from 10 MHz to 25 MHz.
 Two engines were sold with the card: The King by Johann de Koning and Gideon by Ed Schröder.
 Gideon was famed for winning two World Computer Chess Championships on this hardware.
 The King later became the engine used in the popular Chessmaster series of chess programs.
The Iyonix PC was an Acorn-clone personal computer sold by Castle Technology and Iyonix Ltd between 2002 and 2008.
 According to news site "Slashdot", it was the first personal computer to use Intel's XScale processor.
 It ran RISC OS 5 .
The Xerox 820 was an 8-bit desktop computer sold by Xerox in the early 1980s.
 The computer ran under the CP/M operating system and used floppy disk drives for mass storage.
 The microprocessor board was a licensed variant of the Big Board computer.
The Digi-Comp I was a functioning, mechanical digital computer sold in kit form.
 It was originally manufactured from polystyrene parts by E.S.R., Inc. starting in 1963 and sold as an educational toy for US$4.99.
Aztec C is a C compiler for MS-DOS, Apple II DOS 3.3 and ProDOS, Commodore 64, early Macintosh, CP/M-80, Amiga, and Atari ST.
The Amiga is a family of personal computers sold by Commodore starting in 1985.
 The original model was part of a wave of 16 and 32 bit computers that featured 256KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio over 8-bit systems.
 This wave included the Atari ST—released the same year—Apple's Macintosh, and later the Apple IIGS.
 Based on the Motorola 68000 microprocessor, the Amiga differed from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS.
Dushawne Simpson is an American soccer coach, currently coaching with Aztec Soccer.
 Simpson coaches the Aztec U13,U16 and Aztec U23 WPSL team.
 He also serves as the Aztec youth club's Director of Coaching.
 Simpson has been a part of two national championship teams with Aztec and just recently a regional and national finalist with his U17G and U23 women.
 Simpson also recently led his girls high school team Pingree to a NEPSAC Class C Championship.
The SPARCstation 2, or SS2 (code named "Calvin") is a SPARC workstation computer sold by Sun Microsystems.
 It is based on the sun4c architecture, and is implemented in a pizza box form factor.
The Visual 1050 was an 8-bit desktop computer sold by Visual Technology in the early 1980s.
 The computer ran under the CP/M operating system and used 2 400KB, 5¼, SSDD, 96tpi floppy disk drives (TEAC FD-55E) for mass storage with an optional 10Mb external Winchester hard disk drive.
 In addition to the Zilog Z80 processor clocked at 4 MHz, the Visual 1050 also included a MOS Technology 6502 used as a graphics coprocessor.
