[GreenKeys] M28 Manual Message Address Segregator VSL 578 manual

[Nick England]

Have you ever seen one of these in operation or have any pictures of one in
service?
A buddy talked me into taking home one of these, but it is missing the
TP329324 Switching Control Assembly. If you happen to have a spare, please
let me know.

Also I need the 1216B parts book.

        The segregator normally operates in conjunction with the "tape
factory" of a Torn Tape Message Relaying System that includes from one to
eight reperforators and a monitor printer. The monitor printer, when
connected to its designated loop, will copy all characters transmitted by
the segregator. The segregator supplies nine separate loops, one for each
reperforator and one for a monitor printer. Only the manually selected
reperforators will operate and they will then punch only the addresses
manually directed to them.
      The basic function of the segregator is to transmit messages with
manually selected addresses fro each reperforator from a multiple addressed
message tape. The segregator transmits at a rate of 107 wpm (75 baud) to
any combination of up to 8 external reperforators. Selection (all
switching) is accomplished through the use of the switching control
assembly which is placed with the transmitter-distributor on top of the
segregator table.
       Selection of the reperforators that are to receive from the
segregator is made by operation of a control assembly SELECT lever
(lighted) for each reperforator. Selection of the dc loop with its
associated reperforator that is to receive a specific address is made by
operation of the control assembly rotary CONNECT switch.
     The segregator eliminates only those addresses that are not wanted for
each individual reperforator . Each address in the multiple addressed tape
is manually directed to only those reperforators that require it. An
external reperforator will punch both address and message in tape only if
its SELECT lever is operated and either its loop or all loops are connected
by the rotary CONNECT switch on the switching control assembly.
      Addressed message transmission is accomplished by means of the
Self-Contained Transmitter Distributor Set (LXD Type) of the segregator.
This transmitter distributor set has special code reading contacts and
includes the proper base, synchronous motor unit, TP173595 gearset, cover,
and cables.
     All line (loop) switching and reperforator selection is accomplished
manually by means of the TP329324 switching control assembly. The SELECT
levers that are operated to select a reperforator are also illuminated
