CTI is a Dutch softwarehouse that has been using AT&T 3B2 computers in the
past 4 years. As you may know AT&T has a marketing agreement with Olivetti
in Europe. The Italians are not very supportive and do not want to position
the 3B2 versus their own LSX-baby. Other than by this Italian connection, the
AT&T computer division is not represented in Europe.
We are looking for a possibility to import AT&T computers from the US to
Holland and we would like to receive offerings from US-based AT&T VAR's.
We are particularly interested in the 3B2-range and powerful 80386-boxes with
the Unix system V/386 operating system.
Please forward information and quotations by e-mail or snail mail.

I have had exactly this problem before. In my case, I swapped parts from a
known working system until I had replaced the entire machine, and it still
would not work. The reason I found in the end was that the cable from the
terminal to the console port had got damaged, the machine was not seeing a
complete set of hardware handshaking lines, and so refused to play ball.
Try swapping the console cable for another one which you know works, and
also put a breakout box on the terminal to check whether all the necessary
handshaking lines are being generated. It may cure the problem.

Is the rs232 NAU different from the std NAU? The NAUs in my 3B2/400s
each have a "hole" marked "phone" (I think) but I didn't find any
documentation on how or what. What can you tell me?
Thanks.

The RS232 NAU is an external stand alone device which allows one to
interface standard rs232 devices onto a starlan network. It provides
support for terminals and modems. It's really a nifty device,allowing
one to have a starlan printer,data terminal,modem directly attached to
the net.. I haven't received mine yet,but when I do, I'll know more.
