The AT&T UnixPC was AT&T's attempt to get into the business computer market of the mid-1980s. There were two flavors of this machine: the 7300, and the 3B1. Basically the circuitry is identical in both machines however the 3B1 allowed more room for hard-drive storage, as shown with the ominous bulge underneath the screen. (not shown in model above).
The windowing manager was absolutely wonderful keeping the UNIX system well hidden, however, you could naturally open a shell and interface directly. The graphics system was neat as well - there is a 3D bitmap demo online somewhere.
These computers could support 3 terminals with an add-on card for concurrent use by up to 4 users (one at he console, one on the built-in port, and one each on the two add-on ports).
The keyboard could be "nested" on the shelf in front of the floppy drive. The sound was limited to beeps.
There was also an add-on board with a speech synthesizer which could turn the UnixPC into a full-fleged voicemail management system.
An absolutely wonderful and advanced computer for it's time, which can still teach modern computers a lesson in innovation.

We need more info about this computer ! If you designed, used, or have more info about this system,
please send us pictures or anything you might find useful.
This looks like the beginning of UNIX/LINUX/BSD for the home computer user.
Emulators don''t work. I am bumbed :-(
But over the years all the software on this system has already been ported and updated to all corners of the round earth. :-)

The voice mail board you describe was called "Voice Power''. It was one of the first menu-directed systems. 3B1 systems could have several boards. It had text to speech as well.

This is such a fantastic machine. I''ve had one for several years now. Unfortunately shortly after receiving it in working condition, I could not help but to open it up to see the insides. This was a difficult machine to get open, and somehow I have managed to do something to it. It no longer boots, and I do not have the OS to try to restore it to working condition.
