Maybe these words will be useful:
- mc68000 — Motorola 68000
- bs2000 — (operating system) An operating system from SNI for mainframes.
- simcity 2000 — (games) An upgraded version of the game/simulation SimCity by Maxis Software. In the new version you can raise, lower and level terrain; build roads and railways at 45-degree angles; name things in your city by planting "signs"; build raised highways, subways, and train and bus stations, schools, colleges, hospitals, electricity, water, recreational marinas and zoos. There are three levels of zoom, and the view may be rotated to look at your city from any of the four directions. A query feature which will tell you the zoning, land value, etc. of any square. You get newspapers, advice from council members, graphs, and charts.
- mcp-1600 — A processor made by Western Digital, consisting of at least four separate integrated circuits, including the control circuitry unit, the ALU, two or four ROM chips with microcode, and timing circuitry. The ALU chip contained twenty-six 8-bit registers and an 8-bit ALU, while the control unit supervised the moving of data, memory access, and other control functions. The ROM allowed the chip to function as either an 8- or 16-bit chip, with clever use of the 8-bit ALU. Further, microcode allowed the addition of floating-point routines (40 + 8 bit format), simplifying programming (and possibly producing a floating-point coprocessor). Two standard microcode ROMs were available. This flexibility was one reason it was also used to implement the DEC LSI-11 processor as well as the WD Pascal Microengine.
- ns32000 — National Semiconductor 32000
- sinclair pc200 — (computer) 1998-07-28
- tms 9900 — (processor) One of the first true 16-bit microprocessors, released by Texas Instruments in June 1976 (the first are probably National Semiconductor IMP-16 or AMD-2901 bit slice processors in 16-bit configuration). It was designed as a single chip version of the TI 990 minicomputer series, much like the Intersil 6100 was a single chip PDP-8, and the Fairchild 9440 and Data General mN601 were both one chip versions of Data General's Nova. Unlike the IMS 6100, however, the TMS 9900 had a mature, well thought out design. It had a 15-bit address space and two internal 16 bit registers. One unique feature was that all user registers were actually kept in memory - this included stack pointers and the program counter. A single workspace register pointed to the 16 register set in RAM, so when a subroutine was entered or an interrupt was processed, only the single workspace register had to be changed - unlike some CPUs which required dozens or more register saves before acknowledging a context switch. This was feasible at the time because RAM was often faster than the CPUs. A few modern designs, such as the INMOS transputer, use this same design using caches or rotating buffers, for the same reason of faster context switches. Other chips of the time, such as the 650x series had a similar philosophy, using index registers, but the TMS 9900 went the farthest in this direction. That wasn't the only positive feature of the chip. It had good interrupt handling features and very good instruction set. Serial I/O was available through address lines. In typical comparisons with the Intel 8086, the TMS9900 had smaller and faster programs. The only disadvantage was the small address space and need for fast RAM. Despite very poor support from Texas Instruments, the TMS 9900 had the potential at one point to surpass the Intel 8086 in popularity.
- altair 8800 — (computer) An Intel 8080-based machine made by MITS. The Altair was the first popular microcomputer kit. It appeared on the cover of the January 1975 "Popular Electronics" magazine with an article (probably) by Leslie Solomon. Leslie Solomon was an editor at Popular Electronics who had a knack for spotting kits that would interest people and make them buy the magazine. The Altair 8800 was one such. The MITS guys took the prototype Altair to New York to show Solomon, but couldn't get it to work after the flight. Nonetheless, he liked it, and it appeared on the cover as "The first minicomputer in a kit." Solomon's blessing was important enough that some MITS competitors named their product the "SOL" to gain his favour. Some wags suggested SOL was actually an abbreviation for the condition in which kit purchasers would find themselves. The original Altair BASIC ran in less than 4K of RAM because a "loaded" Altair had 4K memory. Since there was no operating system on the Altair, Altair BASIC included what we now think of as BIOS. It was distributed on paper tape that could be read on a Teletype. Later versions supported the 8K Altair and the 16K diskette-based Altair (demonstrating that, even in the 1970s, Microsoft was committed to software bloat). Altair BASIC was ported to the Motorola 6800 for the Altair 680 machine, and to other 8080-based microcomputers produced by MITS' competitors.
- mips r2000 — (processor) The R2000 design came, in about 1987, from the Stanford MIPS project, which stood for Microprocessor without Interlocked Pipeline Stages. Like the AMD 29000, the R2000 has no condition code register considering it a potential bottleneck. The program counter can be read like other registers. The CPU includes an MMU that can also control a cache, and the CPU can operate as big-endian or little-endian. There is a FPU, the R2010. Versions include the MIPS R3000 and MIPS R4000.
