I decided I'd do an article about the Term-Mite for the CHWiki; I found
Ciarcia's long article about the Term-Mite (in his book, which Google books
has); it talks throughout the article about the NS4

Ah, thanks muchly! Do you know of _any_ documentation extant for the 455? I
couldn't find anything..

This is now available through here:
http://gunkies.org/wiki/Term-Mite_ST_Smart_Terminal
I put in a little infrastructure around it (articles on the Term-Mite, NS405,
etc), using info I dug up online.
