Info wanted, Congruent/Uniys machines

Hi, I have a couple of systems given to me by an accountant friend. They bear a "Congruent" name plate, but the actual name on the S/N - Model # plate, is Unisys. At least one of them is a model CJ-5330-A12. While he was using these, he was running an operating system called C-TIX which is supposedly strictly for accounting type applications, and, he claims, this is the only OS that will run on these. Anybody know any thing about these. This C-TIX looks alot like UNIX as far as OS commands... But... Any help anyone can give me on this, is more than greatly appreciated. AdvaTHANKSnce!

To reply to this message, you must remove the .spamfree from the reply-to address. To those friends, and folks who are trying to contact me with info that I will likely be happy to receive, I apologze for this inconvienence. To those out there, sending all these annoying "junk mail" messages, I say "Oh well...." Will
