What is the difference between a TT-178 & TT-179?

That sounds like a well worth-while project.

I have "1968 glossary of military electronic systems" (all lower case) - 
it lists all kinds of stuff.  For the AN/FGC-25 it says: Army Teletype 
Smith - Corona;P   ( p stands for production vs. S Study, D Development, 
  O opweration; P/O phasing Out).
Real informative.

Another dandy entry:
MARDAN: Navy medium sized computer, scientific application, Autonetics 
OP.  Yeah, no kidding. Inertial Navigation Computer for FBM Submarines...

These lists are often one step (barely) better than nothing- So a real 
list - preferrably with photos - would be really nice.

best regards...
