Yes, that's the one. The system uses Storage Tube technolgy which allow the
system to use vector graphics in overlays up build up a pretty complex drawing
on 32K of memory. The storage tube retains the image with virtually no refresh
and allows a succession of plots to be "overlayed" to build up an image, This
was pretty advanced stuff in 1976.

This unit I got yesterday even has a rs232 interface that allow to be used as
a terminal and has the extra full complement of 32K of mem.

I spent last nite playing with it and improving a digital mapping and plotting
program I wrote on it about 28 years ago...
