  • 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 2741 — (printer)   A slow, letter-quality printing device and terminal based on the IBM Selectric typewriter. The print head was a little sphere resembling a golf ball, bearing reversed embossed images of 88 different characters arranged on four parallels of latitude; one could change the font by changing the golf ball. The device communicated at 134.5 bits per second, half duplex. When the computer transmitted, it physically locked the keyboard. This was the technology that enabled APL to use a non-EBCDIC, non-ASCII, and in fact completely non-standard character set. This put it 10 years ahead of its time - where it stayed, firmly rooted, for the next 20, until character displays gave way to programmable bit-mapped devices with the flexibility to support other character sets.
  • ibm 3270 — (hardware)   A class of terminals made by IBM known as "Display Devices", normally used to talk to IBM mainframes. The 3270 attempts to minimise the number of I/O interrupts required by accepting large blocks of data, known as datastreams, in which both text and control (or formatting functions) are interspersed allowing an entire screen to be "painted" as a single output operation. The concept of "formatting" in these devices allows the screen to be divided into clusters of contiguous character cells for which numerous attributes (color, highlighting, character set, protection from modification) can be set. Further, using a technique known as 'Read Modified' the changes from any number of formatted fields that have been modified can be read as a single input without transferring any other data, another technique to enhance the terminal throughput of the CPU. The 3270 had twelve, and later twenty-four, special Programmed Function Keys, or PF keys. When one of these keys was pressed, it would cause the device to generate an I/O interrupt and present a special code identifying which key was pressed. Application program functions such as termination, page-up, page-down or help could be invoked by a single key-push, thereby reducing the load on very busy processors. A version of the IBM PC called the "3270 PC" was released in October 1983. It included 3270 terminal emulation. See also broken arrow.
  • 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.
  • ieee 802 — (networking, standard)   The IEEE standards for local area networks. The spanning tree algorithm is defined in IEEE 802.1 (under consideration), Logical Link Control (LLC, the upper portion of the data link layer) in IEEE 802.2, Ethernet in IEEE 802.3, Token Bus in IEEE 802.4 and IBM Token Ring in IEEE 802.5.

  • modula-2 — (language)   A high-level programming language designed by Niklaus Wirth at ETH in 1978. It is a derivative of Pascal with well-defined interfaces between modules, and facilities for parallel computation. Modula-2 was developed as the system language for the Lilith workstation. The central concept is the module which may be used to encapsulate a set of related subprograms and data structures, and restrict their visibility from other portions of the program. Each module has a definition part giving the interface, and an implementation part. The language provides limited single-processor concurrency (monitors, coroutines and explicit transfer of control) and hardware access (absolute addresses and interrupts). It uses name equivalence.
  • oberon-2 — (language)   A superset of Oberon-1, developed by H. Moessenboeck in 1991 to add object-orientation. Oberon-2 was a redesign of Object Oberon. It included type-bound procedures (equivalent to methods), read-only export of variables and record fields, open array variables, and a "with" statement with variants. It reintroduced the "for" statement. There is an Oberon-2 Lex scanner and Yacc parser by Stephen J Bevan of Manchester University, UK, based on the one in the Mo"ssenbo"ck and Wirth reference. Version 1.4.
  • prolog-2 — An implementation of Edinburgh Prolog by Nick Henfrey, ESL.
  • rca 1802 — (processor)   An extremely simple microprocessor fabricated in CMOS, running at 6.4 MHz at 10V (very fast for 1974). It could be suspended with the clock stopped. It was an 8-bit processor, with 16-bit addressing. Simplicity was the primary design goal, and in that sense it was one of the first RISC chips. It had sixteen 16-bit registers, which could be accessed as thirty-two 8-bit registers, and an accumulator D used for arithmetic and memory access - memory to D, then D to registers and vice versa, using one 16-bit register as an address. This led to one person describing the 1802 as having 32 bytes of RAM and 65535 I/O ports. A 4-bit control register P selected any one general register as the program counter, while control registers X and N selected registers for I/O Index and the operand for the current instruction. All instructions were 8 bits - a 4-bit op code (total of 16 operations) and 4-bit operand register stored in N. There was no real conditional branching, no subroutine support and no actual stack but these could be implemented by clever use of registers, e.g. changing P to another register allowed jump to a subroutine. Similarly, on an interrupt P and X were saved, then R1 and R2 were selected for P and X until an RTI restored them. The RCA 1805 was an enhanced version. The 1802 was used in the COSMAC (VIP?) microcomputer kit, some video games from RCA and Radio Shack, and the ETI-660 computer. It was chosen for the Voyager, Viking and Galileo space probes as it was also fabricated in Silicon on Sapphire, giving radiation and static resistance, ideal for space operation.
  • rfc 1112 — (networking, standard)   The RFC describing MBONE.
  • rfc 1123 — (networking, standard)   The RFC "Requirements for Internet Hosts Application and Support" which clarifies or changes the specification of protocols given in earlier RFCs. RFC 1123 defines the terms "MUST", "SHOULD", "MAY", "unconditionally compliant", "conditionally compliant". Capitals are used to emphasise that the official definition of the word is being used. MUST or REQUIRED means an absolute requirement for conformance. SHOULD or RECOMMENDED means the item can be ignored under certain circumstances, although the full implications should be understood. MAY or OPTIONAL means the implementor can choose, usually depending on whether it is needed or not. Something "unconditionally compliant" meets all the MUST and SHOULD requirements, "conditionally compliant" meets all the MUST requirements and "not compliant" - does not meet some MUST requirement. For example, RFC 1123 amends RFC952 to say software MUST handle either a letter or a digit as the first character of a hostname.
