- clubmen — Plural form of clubman.
- ibm 360 — System/360

- ibm 650 — (computer) A computer, produced ca. 1955 and in use in the late 1950s, with rotating magnetic drum storage and punched card input. Its memory words could store 10-digit decimal numbers and each instruction had two addresses, one for the operand and one for address of the next instruction on the drum.
- ibm 701 — (computer) ("Defense Calculator") The first of the IBM 700 series of computers. The IBM 701 was annouced internally on 1952-04-29 as "the most advanced, most flexible high-speed computer in the world". Known as the Defense Calculator while in development at IBM Poughkeepsie Laboratory, it went public on 1953-04-07 as the "IBM 701 Electronic Data Processing Machines" (plural because it consisted of eleven connected units). The 701 was the first IBM large-scale electronic computer manufactured in quantity and their first commercial scientific computer. It was the first IBM machine in which programs were stored in an internal, addressable, electronic memory. It was developed and produced in less than two years from "first pencil on paper" to installation. It was key to IBM's transition from punched card machines to electronic computers. It consisted of four magnetic tape drives, a magnetic drum memory unit, a cathode-ray tube storage unit, an L-shaped arithmetic and control unit with an operator's panel, a punched card {reader, a printer, a card punch and three power units. It performed more than 16,000 additions or subtractions per second, read 12,500 digits a second from tape, print 180 letters or numbers a second and output 400 digits a second from punched-cards. The IBM 701 ran the following languages and systems: BACAIC, BAP, DOUGLAS, DUAL-607, FLOP, GEPURS, JCS-13, KOMPILER, LT-2, PACT I, QUEASY, QUICK, SEESAW, SHACO, SO 2, Speedcoding, SPEEDEX.
- ibm 704 — (computer) A large, scientific computer made by IBM and used by the largest commercial, government and educational institutions. The IBM 704 had 36-bit memory words, 15-bit addresses and instructions with one address. A few index register instructions had the infamous 15-bit decrement field in addition to the 15-bit address. The 704, and IBM 709 which had the same basic architecture, represented a substantial step forward from the IBM 650's magnetic drum storage as they provided random access at electronic speed to core storage, typically 32k words of 36 bits each. A typical 700 series installation would be in a specially built room of perhaps 1000 to 2000 square feet, with cables running under a raised floor and substantial air conditioning. There might be up to eight magnetic tape transports, each about 3 x 3 x 6 feet, on one or two "channels." The 1/2 inch tape had seven tracks and moved at 150 inches per second, giving a read/write speed of 15,000 six bit characters (plus parity) per second. In the centre would be the operator's console consisting of cabinets and tables for storage of tapes and boxes of cards; and a card reader, a card punch, and a line printer, each perhaps 4 x 4 x 5 feet in dimension. Small jobs could be entered via punched cards at the console, but as a rule the user jobs were transferred from cards to magnetic tape by off-line equipment and only control information was entered at the console (see SPOOL). Before each job, the operating system was loaded from a read-only system tape (because the system in core could have been corrupted by the previous user), and then the user's program, in the form of card images on the input tape, would be run. Program output would be written to another tape (typically on another channel) for printing off-line. Well run installations would transfer the user's cards to tape, run the job, and print the output tape with a turnaround time of one to four hours. The processing unit typically occupied a position symmetric but opposite the operator's console. Physically the largest of the units, it included a glass enclosure a few feet in dimension in which could be seen the "core" about one foot on each side. The 36-bit word could hold two 18-bit addresses called the "Contents of the Address Register" (CAR) and the "Contents of the Decrement Register" (CDR). On the opposite side of the floor from the tape drives and operator's console would be a desk and bookshelves for the ever-present (24 hours a day) "field engineer" dressed in, you guessed it, a grey flannel suit and tie. The maintenance of the many thousands of vacuum tubes, each with limited lifetime, and the cleaning, lubrication, and adjustment of mechanical equipment, was augmented by a constant flow of bug reports, change orders to both hardware and software, and hand-holding for worried users. The 704 was oriented toward scientific work and included floating point hardware and the first Fortran implementation. Its hardware was the basis for the requirement in some programming languages that loops must be executed at least once. The IBM 705 was the business counterpart of the 704. The 705 was a decimal machine with a circular register which could hold several variables (numbers, values) at the same time. Very few 700 series computers remained in service by 1965, but the IBM 7090, using transistors but similar in logical structure, remained an important machine until the production of the earliest integrated circuits.
- ibm 705 — (computer) A business-oriented counterpart of the IBM 704. The 705 was a decimal machine with a circular register which could hold several values at the same time. Languages incuded ACOM, Autocode, ELI, PRINT, PRINT I, SOHIO, SYMBOLIC ASSEMBLY.
- ibm 709 — (computer) A computer made by IBM oriented toward scientific work. The 709 had the same basic architecture as the IBM 704 but with many I/O and performance refinements over the 704. The IBM 709 (like the 704) had 36-bit memory words, 15-bit addresses and instructions with one address. A few index register instructions had the infamous 15-bit decrement field in addition to the 15-bit address. The IBM 7090 was a transistorised version of the 709.
- ibm 801 — The original IBM RISC processor, developed as a research project. It was named after the building in which it was designed.
- submiss — submissive.
- webmail — E-mail that is available for use online and stored in the Internet server mailbox, and that is not downloaded to an e-mail program or used offline.
