NCR tower32 - test-drb@ccmp.vtda.org

   My friend has
found a NCR Tower32 machine, seems to be
 build around a motorola 68020 board with a vme bus, it
 has a number of dsub 15pin ports on tha back, seems to be
 somekind of terminal interface.

 Well, I don't know a whole lot about the machine, but basically:

     * The 15 pin ports are proprietary serial ports for the NCR
     terminals. I don't know if they can be broken out to something
     more standard or if the system needs anything special that
     the NCR terminals provide.

I had a NCR tower with the 15 pin ports and didn't have TOO much trouble
connecting a terminal. Basically, I was able to trace the leads back to the
drivers (1488 / 1489) and determine which pins were for output and which
were for input.

It's basic RS232 stuff except the pinouts are funky.
