Regarding the ZTX-1-A, thanks to those who responded. I just found the description of it in the Summer, 1982 issue of Sextant. Turns out it is a Smart Communications Terminal that was officially announced at the 1982 West Coast Computer Faire. It has its own internal 300 baud modem, and is used with the Zenith ZVM video monitor, and was priced at $695. It does contain an internal battery so the unit can "remember" the names and phone numbers that are input. On a side note, when I opened up the case and saw the battery, it was just starting to corrode and would have eventually ended up ruining the circuit board. So just a reminder to all that if you are going to store computers that have batteries in them, it would be a VERY good idea to remove the batteries. In this case, the battery was soldered onto the board and I just cut the wires and put the battery in a zip-lock bag to be kept with the unit. This way if I ever go to get the unit running again, I will know what the proper battery is. I probably wouldn't remove nicads though unless the unit was going to be stored for an unknown (long) period of time and I suspected the nicads were over about 5 years old.
