Aha. Perhaps your friend should try a FOIA request then? Not sure
that would work.

Ask Continental Computers, they should still have some. Talk to Lidan.

I've never heard of people using DB25 for 20mA, at least historically,
contemporaneous with its widespread actual use. E.g. DEC universally used
'flat' 8-pin Mate-n-Lok connectors for 20mA serial connections.

Ah, but isn’t doing what so many before you have had to part of the charm? :)

In my prior life as an EE, I had to do it many times (early 80's)... I may
be nostalgic, but not THAT nostalgic :)

You haven't lived until you have played with live long-line teletype
current loop circuits. In my first job as an FE on a Univac that was a
store and forward message switcher, we had racks of mercury relays
feeding the teletype lines, which ran at 130VDC to give the current
needed to get to the

I've not heard from anyone interested in this system. It's in a rolling,
counter high, rack case. Salt Lake City area. Anyone interested can pick
it up.
If I don't hear from anyone, it's headed to the dump.

Tried the ADM-3A out today on my PDP-8/A via the 20 ma current loop
interface - just unplugged the ASR-33 and plugged in the glass TTY :)
Worked great (the current loop probably had never been used, so no one had a
chance to blow it up), but I got tired of holding down the Shift key since
