For what it's worth, the Kodak tech info is here...

It isn't orthochromatic (so you can't use a red safelight to play with it in the darkroom) so that might be ok in a camera body - but "low-speed" is a bit vague, in the documentation! The base is grey, but if it isn't very dark perhaps you could try contact printing a neg to make a positive, though that would be better done with the positive release-print film. For pictorial Gamma, from the PDF, it looks like about six minutes in D-96 at 21C, but that would depend a lot on exposure I suppose - not to mention the age and storage of the film. Try it and see, and make lots of notes so you know what might have worked on a test roll. Good luck!
