Data Output Decoder. As UN23/25, but uses alternative O/P
1. C. to give inverted logic (especially for Glasgow PCM).
3U CDX single width. Parent equipment BA1/5. DD 1979.
Sequencer Unit. The unit converts two 6 bit parallel
inputs to labelled 8 bit words and provides a serial
output in 20 bit monitoring code. Used in swi tching and
remote control systems. CH1/63. DD 1977.
Machine Control Unit, controls in conjunction with UN23/62
and UN1/185, all machine facilities necessary for automatic
operation of Tape Reclamation Equipment EP1/17.
4U
unsupported board with PN1/29J front panel. DD 1977. DDMI
7.437(80).
Monitor Control Unit, controls in conjunction with UN23/61
and UN1/185, all machine facilities necessary for automatic
operation of Tape Reclamation Equipment EP1/17.
4U
unsupported board with PN1/29J front panel. DD 1977. DDMI
7.438(80).
Manual Override Logic Unit. Contains switches to insert
BCD numbers on to parallel three decade and two decade
outputs. Unit also provides system operating pulses. Part
of instruction decoding system for monitoring and
information centres. 4U unsupported card with B size
panel. DD 1977.
Logic Comparator Unit. Addresses, in three decade BCD
consecutive locations in a read only memory comparing the
20 bit output with a reference word. Search is stopped
when a match is found. This unit forms part of the
instruction decoding system used in Monitoring and
Information Centres. 4U unsupported card with J size fr
ont panel. DD 1977.
Readout "Q" Drive Logic Unit. Data selector switching
eight variable length BCD words to a common bus. Used to
obtain a VDU display of information held in Monitoring and
Information Centre switching stores. 4U uns upported card
with J size front panel. DD 1977.
Qualifier Gating Unit. Part of MIC switching system.
Series of gates to combine the outputs of two qualifier
drive units. CH1/64J. DD 1977.
Readout Control Unit. Part of MIC switching system. Scans
output store units and converts to captions, in ASCII code
for sending to VDU. This provides a table showing the
current conditions. CH1/64J. DD 1977.
Qualifier Verification Unit. Part of MIC switching system.
Used to check that qualifier part of system instruction is
valid. CH1/64J. DD 1977.
Automatic Fault Reporter. Contains internal signals and
drives MIC compatible indications for input to TM1M/1 fault
reporter family. Part of VHF Radio Control and Indication
Panel. CH1/64J. DD 1977.
