HAL DS-3100 ASR

[Mike Stein]

HAL Communications are still around AFAIK and the ham world is usually pretty good about documentation etc.; might be worth sending them an inquiry:
http://www.halcomm.com/

Maybe even try to get in touch with Bill Henry:

I'm not sure about that.. I've been trying to find any documentation I can online about it to understand more about how it works.  I got it for $40 in non-working condition -- turned out it does work.  But detailed info seems to be sparse.

You have rules out that it is not a current loop terminal?
