[GreenKeys] More Bell P3x practices on the way

[Nick England]

Howdy gang - A very kind person recently gave me a box of P3x
Practices, mostly P34.xxx for M28 equipment.
The complete list is at
http://www.navy-radio.com/manuals-ttycorp.htm#pad

I'll work on scanning them over the next few months. Let me know if there
are some you want me to move to the top of the pile.
I'm communicating with Don to avoid any duplication of effort.

Don's succesful Model 14 P35 scans encouraged me to give one a quick try.
http://www.navy-radio.com/manuals/tty/p34.101.pdf
is "28 Teletypewriters - List of Units & Auxiliary Features" which
discusses Bell System model nomenclature. The addendum pages are at the end
of the file - maybe I should put them first?
For example, you can find out that the 28E KSR/RO shelf-mounted cabinet is
like the 28C but has a transformer and two 6v copylamps, with a directory
holder on the left side.

I think next I'll scan the similar TD, reperf, etc. List of Units &
Features in case, like me, you'd like to make heads or tails out of Bell's
numbering scheme.

cheers,
Nick
