A number of IBM machines, modules and devices were used with the IBM System/7, including:
- IBM 129 card data recorder. The 129 card data recorder provided punched card input/output capability for the System/7. One IBM 129 could be attached to an IBM 5013 digital I/O module. Programs and/or data could be read or punched through the IBM 129. In the offline mode, the 129 could be used as a conventional data recorder. The 129 could read up to 50 cards per minute and could punch cards at a rate of from 12 to 50 cards per minute depending on the number of columns punched. An optional feature provided an enhanced card read rate of up to 90 cards per minute. The 129 came in three models: Model 1 -- alphameric, punch-verifier, non-printing; Model 2 -- alphameric, printing punch, non-verify; and Model 3 -- alphameric, printing punch-verifier.
- IBM 2502 card reader. The 2502 card reader Model A2 was attached to the IBM 5024 (see below) Model 2 or Model 3 and was used for automatic entry of punched card data. Cards were read serially by a sensing mechanism which was checked for proper functioning on every cycle. Operation was up to 300 cards per minute.
- IBM 2790 control. This feature provided control for the operation of the IBM 2790 data communication system components. Those 2790 devices provided the System/7 with an extensive range of equipment for data collection and shop floor communications applications. Some of the devices supported by the 2790 control were the IBM 2791 area station (which allowed input from operator identification badges, 80 column punched cards, manual keyboard and customer digital devices); IBM 2792 remote communications controller; IBM 2793 area station; IBM 2796 and 2797 data entry units; IBM 2798 guidance display unit; IBM 1053 printer; and IBM 1035 badge reader.
- IBM 5012 multifunction module. The 5012 contained the interface circuits and housed the optional hardware features needed to implement digital input and output, analog input and output, and process interrupt.
- IBM 5013 digital input/output module. The digital input/output module housed the hardware necessary to implement digital input/output, process interrupt, IBM 2790 control (one per 5013), and expansion capability for selected custom products.
- IBM 5014 analog input module, Model B. This module housed the analog input adapter, analog-to-digital converter, multiplexer, amplifier and associated circuitry to provide a maximum of 128 two-wire input points in groups of 16 points.
- IBM 5014 analog input module, Model C. This module used a solid state differential input multiplexer.
- IBM 5014 analog input module, Model D. This module housed the analog input adapters, analog-to-digital converter, multiplexer, amplifier and associated circuitry to provide a maximum of 128 two-wire input points in groups of 16 points.
- IBM 5014 analog input module, Model E. This module housed the analog input adapter, multiplexer, and associated circuitry to provide a maximum of 128 two-wire input points in eight groups of 16 points. The Model E1 attached to a Model D and provided scan speeds up to 100 points per second; the Model E2 attached to a Model D and provided scan speeds up to 200 points per second. One or two Model E modules could be attached to the appropriate Model B or D.
- IBM 5022 disk storage module. This module provided auxiliary storage for data and programs, initial program load (IPL), and automatic IPL coupled with power failure and auto-restart features. All models (there were four) had one fixed disk with a storage capacity of 1.2 million words; Models 1 and 2 could also accommodate an IBM 5440 disk cartridge to provide a total of 2,457,600 words of online storage and unlimited offline storage capacity.
IBM 5024 input/output attach enclosure. This freestanding enclosure was available in three models:
The 5024 attached to a System/7 containing a Model E processor module via the IBM 5024 attachment feature.
- Model 1 provided the basic enclosure and line printing at speeds up to 155 lines per minute (lpm).
- Model 2 provided for attachment of an IBM 2502 card reader, Model A2, operating at up to 300 cards per minute (cpm).
- Model 3 provided a line printer operating at up to 155 lpm and included attachment of an IBM 2502 card reader, Model A2, operating at up to 300 cpm.
- IBM 5024 line printer. This unit was an integral part of the IBM 5024 input/output attach enclosure, Models 1 or 3. It provided 132 print positions and used an interchangeable print belt with 48, 64 or 96 print positions. Maximum print speed varied from 80 lpm to 155 lpm depending on the character set used.
IBM 7414 interactive console. The interactive console custom product provided a versatile and modular approach to the communication of instructions, data and status between an operator and the System/7. It attached to the standard digital input/output facilities of the System/7 and could be located up to 2,000 feet away to attach the following devices:
- A customer-supplied video monitor to display alphanumeric information for visual communication. Up to 12 lines of 40 characters could be displayed. A color display option could be provided for displaying red, blue, green, yellow, blue/green, purple and white characters on a color monitor.
- An alphameric keyboard with a typewriter keyboard arrangement for data entry. Data was automatically displayed on the video monitor.
- An IBM 1053 printer Model 4 for permanent hard copy of displayed messages.
- A special function keyboard with 24 oversize keys that simplified priority communication with the System/7. These keys could be individually labeled to identify required functions, such as INITIATE EXPERIMENT or ABORT RUN.
- IBM 7431 printer. The 7431 printer provided an 85 character per second serial matrix printer for attachment to the System/7. The printer could be used for program listings, linkage edit memory maps, and application report writing. There were three models of the 7431: Model 1 -- pin feed platen; Model 2 -- vertical forms control; and Model 3 -- vertical forms control and bi-directional printing. The 7431 had a maximum print rate of 85 characters per second, a print line of 132 print solutions, character spacing of 10 characters per inch, and a vertical line spacing of six lines per inch. An optional feature for the Model 3 provided an enhanced print rate of 115 cps. One printer could be attached to an IBM 5013 digital I/O module.
