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:
- 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.
The 5024 attached to a System/7 containing a Model
E processor module via the IBM 5024 attachment feature.
- 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.
