If someone dumps the ROM of the Zentec ADM3 Retrofit, I'll try my hand at
reverse-engineering the code.

This is now available through here:

I put in a little infrastructure around it (articles on the Term-Mite, NS405,
etc), using info I dug up online.

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

I decided I'd do an article about the Term-Mite for the CHWiki; I found
