[GreenKeys] Last old TTy manual

[telegrapher at att.net]

I think this is the last of my older TTY manuals.  It is an AT&T P.90 series book with lots of stuff in it.  As an example i found this:
P90.902 Issue 1, sheet 2 of 2 on the NO. 20 teletypewriter.  It's the wiring schematic or whatever you want to call it for the No. 20 6 unit Perforator and NO. 20 Dist. on XT 39, XT 201 or 19A TTY Table and NO. 20 KSR on 15A, 15N, 15P or XRT 200 TTY Table.  Pretty neat.  All sorts of wiring diagrams for the different configurations.

P90.948 covers "Signaling arrangements, Aux Bell Signal or one or two Aux visual signals operative on upper case "S" Bell Signal.  No. 15 or NO 19 TTY 

Also covers units used with different data and signaling subsets, data sets, TWX operation

15 Type TTY  on 15 Type and NO 19 set with pulling or holding magnets, wiring and equipment or arrangement.

This collection is about 2 1/4 inches think and filled with 14-15-19 and 20 information some of which dates back to 1947.  $50 plus postage.

4 ea "Instruction manual for Station Motor Control" by Tempo Instrument Inc. from Plainview, L.I., New York.  These operate on the "idle line " time process.  $2 ea
