Attached please find Teletype Corporation 50042S
This covers all information for the 177010 Selector Magnet Driver
used with the Models 15, 19, 20, and 28 machines.

Unlike other S specifications this covers component level testing
and complete theory of operation.

(Some of you might want to put this specification on your websites.)

My thanks to Ben Stephens, K9KOM for this...

73,
Don K9TTY

* NOTE: The basic theory of operation might be the same for other
Teletype machines, but the 32, 33, 35, 37, & 38 SMD circuitry is different.
