It was the 5080 series of IBM workstations. I got a Calma branded one
from the Calma auction in 1989? they were made in the
mid 1980s.
They were basically a 6 Mhz AT (286 & 287) mounted vertically in a
larger case. In the other side of the case was a custom graphics
controller of IBM design that ran a Thompson made monitor at
1024X1024. Also had a graphic tablet on a serial port and used the
standard AT keyboard.
Not RT based.
I also saw them come out of Boeing in hte early 90s.
Thanks for the link to the CAD history. It has been very informative.

I am drawing a complete blank on the product numbers (5xxx series?)
but IBM made a series of CAD workstations in the mid-80's. A friend
of mine ran a lab full of them at the University of Wisconsin - Milw
for the Mechanical Engineering department. I didn't think they were
IBM RT based.

Is sort of interesting, too.
