[vcf-midatlantic] Northern Telecom Displayphones

Hi All,

I recently acquired a couple of Northern Telecom Displayphones. They're
neat little telephone terminals with a 7" black and white CRT, 80x24 ANSI
text, built in 300 baud modem, and a RS-232 port that goes to 9600 baud.

I've looked around and haven't found much technical info on them so I
started a site to gather any extra info I can locate. See link below.


If you have a Displayphone model and can dump the EPROMs, I'll add them to
the site. What I've dumped so far is available to download there.

My Plus model is non functional so I'm not sure if the ROM dump is valid. I
have the manual to the Plus model that I will be scanning soon.

Hope this helps some folks.
