Given that it appears to display graphics on the screen, its a bit
more than a "terminal", particularly since it supports color text.  So
you at least have some sort of indexed CLUT frame buffer in there,
along with software to render the measurements into 2D graphics.
Basic getpixel/setpixel graphics, I imagine, probably all done in
software with a simple memory-mapped framebuffer, but definately much
more than what one would think of as just a terminal from this period.
