I stumbled across your question whilst looking for something else. I don't
know much but.......I can tell you that in a Linear Accelerator (used for
treating cancer with high energy photons (X-rays) or electrons, there is
sometimes a system called Portal Vision which allows digital images of the
treatment site to be taken during treatment. For Varian machines, the
cassette holding the image capture device is on a retractable "arm"
controlled by a control system on a GESPAC G-64/96 bus. CPU is MC68HC000 and
the operating system is OS-9. You may have an R arm controller or more
likely some other OS-9 based system.
