think 50 USD for each is fairly reasonable. They are in very, very good working condition taken out of service a number of years ago, stored and finally sold off recently. I picked them up at a government auction, and they are being sold as-is. I know little to nothing about them, and am by no means an expert, you are more than I am...PS. I hope this is ok to offer these here for sale. I looked at the listing, and it seems this kind of device was WAY ahead of its time, so much so that NT didn't do m uch with them, but they are prized for collectors. I hope I can find a nice home for them.Best wishesTodd Nathan These have been discussed previously (you may want to check the list archive) here, but they are basicly all in one voice/data terminals that were indeed ahead of their time. I had one from around '83-'88 I used pretty regularly. They have a built in chicklet style keyboard (if you plug it in, go to the notepad and test that all the keys work), as well as telephone and program related keys up top. Those small unlabled set of keys along the base of the screen are called "soft keys" and are basicly software programmable keys (another advanced feauture for the time). It was capable of connection from 75-1200 baud, and 40 or 80 column vt100 display capabilities (thought you better have good eyesight for the 80 column setting on that tiny screen). It had a speakerphone built in and multi-line capability. The directory storage (which was rather large and capable of user definition) was interesting in that you could differentiate between voice and data calls in an entry, and even store all the modem and terminal settings individually for each entry.
