More seriously, googling brings up this lead on the company: http://www.pgt.com/nuclear/sys4000.html The company logo, as much as it can be made out, appears identical. The company profile gives another hint: "Princeton Gamma-Tech has been a leader in the field of semiconductor gamma- and X-ray detectors for over 30 years." Perhaps the "customer service and Reachback program" would provide an answer.

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. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>
