Paul Cicchetti Entrex Records/History

So, that Frenchtown, NJ auction, from which I acquired our first Entrex 480 system chassis & [some] system boards....Who paid to store these since [what turns out to be] 1981?  

His name was Paul Cicchetti.

There's a lot to say about Paul, as we learned from the items we acquired from his storage units auction, but this one thing is the most relevant.

How does the Entrex/Nixdorf "Trapezoid" Data/Terminal work?

Well, we don't know yet...but we're working on it.  

See Tom Trebisky's pages on reverse-engineering these "Trapezoid" terminals!!

For starters, here's some context to see how it was advertised:
