  • sparcstation 20 — (computer)   A SPARCStation based on the HyperSPARC processor. The 20 is compatible with the earlier SPARCstation 10. It has a clock rate of 100MHz and delivers a SPECfp92 of 127.6. The SPARCstation 20 Model 71 and 712MP uses the 75MHz SuperSPARC processors that give a 35% and 14% boost to SPECint92 and SPECfp92 respectively compared to the 61/612MP.

  • ibm 1620 — (computer)   A computer built by IBM and released in late 1959. The 1620 cost from around $85,000(?) up to hundreds of thousands of dollars(?) according to the configuration. It was billed as a "small scientific computer" to distinguish it from the business-oriented IBM 1401. It was regarded as inexpensive, and many schools started out with one. It was either developed for the US Navy to teach computing, or as a replacement for the very successful IBM 650 which did quite well in the low end scientific market. Rumour has it that the Navy called this computer the CADET - Can't Add, Doesn't Even Try. The ALU used lookup tables to add, subtract and multiply but it could do address increments and the like without the tables. You could change the number base by adjusting the tables, which were input during the boot sequence from Hollerith cards. The divide instruction required additional hardware, as did floating point operations. The basic machine had 20,000 decimal digits of ferrite core memory arranged as a 100 by 100 array of 12-bit locations, each holding two digits. Each digit was stored as four numeric bits, one flag bit and one parity bit. The numeric bits stored a decimal digit (values above nine were illegal). Memory was logically divided into fields. On the high-order digit of a field the flag bit indicated the end of the field. On the low-order digit it indicated a negative number. A flag bit on the low order of the address indicated indirect addressing if you had that option installed. A few "illegal" bit combinations were used to store things like record marks and "numeric blanks". On a subroutine call it stored the return address in the five digits just before the entry point to the routine, so you had to build your own stack to do recursion. The enclosure was grey, and the core was about four or five inches across. The core memory was kept cool inside a temperature-controlled box. The machine took a few minutes to warm up after power on before you could use it. If it got too hot there was a thermal cut-out switch that would shut it down. Memory could be expanded up to 100,000 digits in a second cabinet. The cheapest package used paper tape for I/O. You could also get punched cards and later models could be hooked up to a 1311 disk drive (a two-megabyte washing machine), a 1627 plotter, and a 1443 line printer. Because the 1620 was popular with colleges, IBM ran a clearing house of software for a nominal cost such as Snobol, COBOL, chess games, etc. The model II, released about three years later, could add and subtract without tables. The clock period decreased from 20 to 10 microseconds, instruction fetch sped up by a few cycles and it added index registers of some sort. Some of the model I's options were standard on the model II, like indirect addressing and the console teletype changed from a model C to a Selectric. Later still, IBM marketed the IBM 1710. A favorite use was to tune a FM radio to pick up the "interference" from the lights on the console. With the right delay loops you could generate musical notes. Hackers wrote interpreters that played music from notation like "C44". 1620 consoles were used as props to represent Colossus in the film "The Forbin Project", though most of the machines had been scrapped by the time the film was made.
  • ibm 3720 — (hardware)   A communications controller made by IBM, suitable for use in an IBM S/390. Official service support was withdrawn in 1999 in favour of the IBM 3745.
  • intersil 6120 — (processor)   (IMS 6120) An improved version of the Intersil 6100. The 6120 was used in the DECmate.
  • rfc 1520 — (networking, standard)   The RFC defining Classless Inter-Domain Routing.

  • 68020 — Motorola 68020
  • motorola 68020 — (processor)   A microprocessor from Motorola. It was the successor to the Motorola 68010 and was followed by the Motorola 68030. The 68020 has 32-bit internal and external data and address buses and a 256-byte instruction buffer, arranged as 64 direct-mapped 4-byte entries[?]. The 68020 added many improvements to the 68010 including a 32-bit ALU and external data bus and address bus, and new instrucitons and addressing modes. The 68020 (and 68030) had a proper three-stage pipeline. The new instructions included some minor improvements and extensions to the supervisor state, some support for high-level languages which didn't get used much (and was removed from future 680x0 processors[?]), bigger (32 x 32-bit) multiply and divide instructions, and bit field manipulations. The new adderessing modes added another level of indirection to many of the pre-existing modes, and added quite a bit of flexibility to various indexing modes and operations. The instruction buffer (an instruction cache) was 256 bytes, arranged as 64 direct-mapped 4-byte entries. Although small, it made a significant difference in the performance of many applications. The 68881 and the faster 68882 FPU chips could be used with the 68020. The 68020 was used in many models of the Apple Macintosh II series of personal computers and Sun 3 workstations.

  • pdp-20 — The most famous computer that never was. PDP-10 computers running the TOPS-10 operating system were labelled "DECsystem-10" as a way of differentiating them from the PDP-11. Later on, those systems running TOPS-20 were labelled "DECSYSTEM-20" (the block capitals being the result of a lawsuit brought against DEC by Singer, which once made a computer called "system-10"), but contrary to popular lore there was never a "PDP-20"; the only difference between a 10 and a 20 was the operating system and the colour of the paint. Most (but not all) machines sold to run TOPS-10 were painted "Basil Blue", whereas most TOPS-20 machines were painted "Chinese Red" (often mistakenly called orange).
  • vic-20 — (computer)   A home computer made by Commodore with a 6502 CPU, similar in style to the Commodore 64 and Commodore C16. The VIC-20 was released before the C64, and after the Commodore PET(?). It was intended to be more of a low-end home computer than the PET. The VIC-20 had connectors for game cartridges and a tape drive (compatible with a C64). It came with five kilobytes of RAM, but 1.5 KB were used by the system for various things, like the video display (which had an unusual 22x20 char/line screen layout), and other dynamic aspects of the operating system (such as it was). The RAM was expandable with a plug-in cartridge which used the same expansion port as games. Port expander boxes were available to allow more than one cartridge to be connected at a time. RAM cartridges were available in several sizes: 3K, 8K, 16K and 32K. The internal memory map was re-organised with the addition of each size cartridge, leading to the situation that some programs would only work if the right amount of memory was available. The 32K cartridges were all third-party and had switches to allow the RAM to be enabled in sections so that any expansion size could be achieved. The name "VIC" came from the Video Interface Chip that was also used in the other, later, Commodore 8-bit computers.
