[GreenKeys] UT-4B help needed

[Gary Buda]

I'm looking for help with a UT-4B that I am planning on putting on ebay.  It 
was sold to me as a working unit.  It arrived in the mail with two wires 
loose.  (I think one wire came loose and was a cold solder joint that came  
off a relay for the TD control) and another loose wire that had a section 
removed from it.  Thanks to the color coding, the loose wire with a chunk 
missing goes from the clock to the UART board, but I cannot imagine why the 
chunk of wire was removed.  

Anybody have the board pin-outs?  This unit came with no documentation.  The 
schematic on rtty.com of the UT-4 is helpful, but circuit board pin-outs would 
be even better.  This is the second UT-4 I've owned.  The first one I built 
(if you have it and the matching ST-6 with a built-in and filtered scope 
monitor, I'll buy them back!)  and whoever built this UT-4 did a fine job but 
I've got a puzzle on my hands to try and solve before trying to peddle the 
unit.  If I can't solve it, I guess I'll part out the unit as there are a 
couple relays, a nice regulated power supply and a bunch of switches I can put 
to use elsewhere.
