I also built an adapter to read the strange EPROMs on the Cinematronics boards.
Sundance was really strange. But I have them packed away and I don't remember
what configuration we eventually ended up with. I took all chip select lines of
the 9316 and had jumpers that allowed me to invert them, or not.
I then read the ROMs, and played with the jumpers until a valid image showed up.
They were not programmed to the "typical" configuration that was shown on the
9316 datasheet.

Sure, I'll take whatever you have, plaster your name and "Thank you"s all over
them and post it all!

Ya, someday some archeologist, on dig, is going to find that picture, carefully
pick it up and turn to her colleague and say: "Here's just what you looking
for!", he'll gingerly take our picture, wad his gum up in it and throw it in the
corner, and say "Thanks, that's just what I needed.". We'll be immortal!
