[GreenKeys] Newbie with an AN/UGC-74A

[Edward Safir]

Hi, I'm new to this list.  I recently bought an AN/UGC-74A.  Mine is in
pretty good shape but suffered from the melted roller issue that appears to
be common with these.  I cleaned up most of the goop, replaced the rubber
on the rollers with some neoprene tubing, replaced the ink ribbon, and the
machine seems to be working fine.  The question now is what to do with it.
While I have been interested in RTTY on and off for many years, I am new to
these older machines, current loops, etc.  I'd like to have it print from
my HAL-CT2200 decoder, which has both current loop and RS-232 connections.
I assume that for a current loop connection, I would use pin G, REC DATA
HI, and pin S, SIGNAL RTN, on the J1 data connector.  Is that correct?  I
also understand that the DATA LO connections on the UGC-74 are for MIL-188,
which is similar to, but not quite, RS-232. Any help would be very much
appreciated.
