A few comments  -
1. The AC power cord connector is MS3116F14-5SW (note the W orientation, a 5S will not work).
A power cord is probably not included since it is listed as NOT INCLUDED in the manual
If you don't want to spend $25 or so for a connector on eBay, it is easy to use a few old molex or tube pin connectors and do this

pins A, B are AC line, pin C is gound.

2. The ribbon/cartridge is no longer available AFAIK.
If you are lucky, your machine may come with a ribbon. Be prepared to keep and cherish it and re-ink it. If you get an extra please share with your less fortunate buddies. I only have 3-4 used cartridges left, but greenkeyer John Toebes is going to create a 3D model so that someone can 3D print more.
Will keep you posted on this.

My 136AX came with no ribbon so I printed on carbonless paper until Glenn WB4UIV gave me a box of used ribbons that he had accumulated while serving aboard submarines. A couple of years ago I sent two dozen of those to the US Navy because they couldn't find any new cartridges to use aboard their missile subs.....

3. The UGC-136 will not run 45 baud (60wpm) so you cannot use it for normal ham radio RTTY or our military RATT net unless you have a speed converter TU to run it at 50 baud or 75 baud - but remember you can use ITTY-100 and W1AN files at 75 baud for testing and demo purposes. Perhaps someone will make a little speed converter board using a PIC or Arduino or whatever.

4. The interface is MIL-STD-188 low level signaling (+/-6v). It will probably work OK for EIA RS-232 but I have no experience with that.
It will NOT work with any 20ma or 60ma current loop.

So had a chance today (07/14/2025) after work to go thru most of the
boxes Jon N5MHI came out to give a hand. Did not open all, just picked a
random few, mainly ones on a pallet that had loose tape or was already
open.   Four  of the boxes that came in were already open and missing
some of the packing material, so those will be held for local pick up
only.  We have a mix of what appears to be NOS , factory sealed and
units that went thru the repair facility and had items that were in need
of replacement taken care of.    So far they all look to be in excellent
condition.

     I will end up re-taping  a lot of the boxes to be sure that they do
not come open in transit, and possibly add some carton strapping to them
to help reinforce the boxes.  the tape that is on all of them is either
paper or a mil grade "duct" tape, all which is kind of brittle,
1992-1998+/- vintage.  the ones we looked at are packed very well, using
expanding foam and plastic liner and the units themselves are sealed in
a silver static vacuum bag. The only ones that were not in a  silver
vacuum bag were the 2 that GOVPLANET had out for pics.

     I will try to update the list tomorrow, has been a long day today.
We have had more request than machines,  Hopefully we can get one to all
those I have on the list so far.  Have had still interest in these as 
of today with a few new emails .  It will be the next box up that goes
out to each member, so no ability to request one box over the other is
not a choice.


  I feel the easiest way for me would be for each member to take care of
shipping from their end and send me the  label to put on the box, that
way it keeps my cost down and less transfer of money. We have FedEx by
every day picking up, we dont use UPS that often so  they wont pick up ,
but I drive by a UPS store every day so could drop off if that is
preferred.  Have not inquired about a price to ship a pallet to another
location to be re-distributed, limited to six machines on a pallet due
to their size and std pallet sizing.

  Will put my paypal and venmo info in the next email, or if you prefer,
sending a check is ok, but will not ship till check clears.  Like I
mentioned the current cost per unit is just under $80.00, so that or
anything over is fine.  Not looking to make money on this, just to 
recover my cost and save them from the landfill. My address is good on QRZ.
