Who makes these terminals?

[Anne Chenette]

I need to know the manufacturers of some terminals for copyright-type
reasons.  What I have is a list of terminal names or "nicknames":
 
        Ampex 230 
        Beehive Superbee 
        Concept-100 
        Hazeltine (terminal) 
        Heathkit h19
        Lear-Siegler (LSI?) ADM-3a 
        Microterm ACT-IV 
        Microterm Mime
        NCR 7900 
        Perkin Elmer Owl 
        Tektronix 4010 and 4025 
        Teleray 1061 
        Televideo (TVI) 912 
        Wyse 50, 75, and 350 
 
What I need is:
 
        (1) the real name of each terminal,
        (2) the name of the company that manufactures it, and 
        (3) the city the company is in, if the company still exists
            (the company's phone number would be even better)
             
Can anyone help me out?  If so, please send mail (no need to clutter the net
with this silliness....).
				Thanks,

P.S.  In case you're dying of curiosity, these terminals are all
      mentioned on the terminfo(4) man page (or associated documentation).
