- ibm 1130 — (computer) A computer introduced by IBM in 1965. It was their cheapest computer to date, and was aimed at price-sensitive, computing-intensive technical markets like education and engineering. It notably included inexpensive disk storage. Non-IBM clones were produced.
- ibm 1403 — (printer) A printer used with the IBM 360 mainframe, a successor to the 1401.
- 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 1710 — (computer) An IBM 1620 with additional features useful for industrial process control: A/D convertors, D/A convertors, general-purpose I/O lines, and interrupts.
- 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.

- 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.
- 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.
- rca 1805 — A later, enhanced version of the RCA 1802. It added several Forth language primitives.

- 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.
