[GreenKeys] AN/UGC-129(V)1

[Tom-WB3AKD]

Folks,

I have three of these "gems" and, the teletype bug having bitten again 
recently, I have managed to get two working about as well as I can tell 
they're supposed to.  The third has become a bit of an organ donor but 
should be repaiable.  I have a few questions:

1)  Anyone have a schematic they could share?  I understand the whole manual 
is very large, and the
manual scanned by W6GER, unfortunately, does not include a schematic, 
although it was quite useful.

2)  Keyboard problem: Does not lock in the compose mode, and this follows 
the keyboard when swapped to another machine.  Seems like it is not getting 
some feedback signal from the  processor.  Is this a common problem?

3)  Flourescent diplay problem.  Again, follows the display when swapped. 
Looks like some of the decoders may have bad outputs as the same dots in all 
segments are dark, even with "RESET"  pressed.

Been through the '05 archives so I know I'm not the only '129 owner here.

Meantime, I guess I'll look for cold solder joints or grease the 15 or 
something.


73,

Tom
