modern internet. I finally found a picture of an
Evans & Sutherland
Picture System 300, for instance.
Alternatively you could have asked here. I own a PS/390, along with the
monitor, keyboard, twiddlebox, tablet, 3D imager and PAL encoder.
I can't easily send you pictures, but I can describe the system. Give me
a bit of time and I could be convinced to pull the boards and describe
those too.
