[GreenKeys] AN/UGC 74A and 74B

[Don Robert House]

Larry,

Both of mine work like new.  The military still is ordering ribbon  
cartridges for these.
In certain environments with heat and sand the Army has had lots of  
failures of computers.
My friend Warren Brader was training soldiers on using the 74B and 74C  
back in Iraq.

I have had the same problem as you are writing about with Model 40  
printers.  I have not
figured out exactly what happens but I believe it is a combination of  
the type of lubricant,
the type of ink in the ribbon, plus heat and the composition of the  
platen.

My UGC-74A and B are in my nice cool basement and I do not run them  
very much.
The military, of course, has the advantage of being able to replace  
parts much easier
than you or I do.

Good luck,
Don
