[GreenKeys] 28ASR questions

[Don Robert House]

There were many 28ASRs in dial TWX service.  They used a 101A or 101B  
Dataset (modem)  M19, M15 were also used on dial TWX.  Western Union  
inherited these machines from the Bell System when the courts decided  
we had to give the service to WUT.  I would gladly trade one of my  
28ASRs for a ASR equipped with a call control unit and a dataset.   
They are rare, rare, rare.

Hi folks:

We have a new guy on greenkeys, Fred Tegge, who has a 28ASR he wishes  
to get operational.  I chatted with him a bit, but I don't know that  
much about the 28 line.  My KSR and TD run, and I can answer  
questions about those, but my ASR is still sitting untouched in the  
garage, so I can't help him out too much.  Fred is going to get me  
some pics to post so we can see what he has, but here is the initial  
set of questions/observations:

- this is a WU machine, originally connected to a phone line, which I  
suppose makes it a TWX machine.  I have not heard of TWX 28ASRs -- I  
presume that there is a dataset (modem) sitting in the base  
somewhere, which I would guess connects to the machine loop interface  
on a terminal block somewhere.  Does anyone have any knowledge of the  
TWX version?  How would one go about disconnecting the dataset to  
allow normal loop operation?  Can you point Fred to specific  
locations on a terminal block for this?

- there is a test switch of some sort, which, in one position allows  
the machine to run open, and in the other position quiets it down,  
but he cannot type, presumably the keyboard is isolated form the  
selector magnets for full-duplex  use.

- on the typing reperf, he asked me a simple question: how to load  
the tape.  I have several sitting around here, but I have never used  
one.  I tried to feed a bit of tape down the chute but was unable to  
get it to feed through.  What's the trick on this?  I need to dig  
through some boxes to find some buried ASR docs.

I'm feeling a bit foolish, since I could not help him out much, but  
I'm sure there are many folks out there who can.

Also, Fred wishes to get a radio/tu setup running, and he wanted to  
know more about the 14 MC stuff that has been going on -- what's the  
update on that?  And by the way, where is everyone located?  I'm  
thinking you are all on the east coast -- here in AZ I have not been  
able to pick any of you up, but Fred is in WI and may have a better  
chance.

Any insight appreciated.

thanks,

gil
