If I'm not mistaken, this one was built for us when I was with Martin Marietta, working on a JPL project to militarize uVAX-II hardware in our customized packaging. It works with VMS, and I doubt there was little else done with it in conjunction with our project. I worked on other parts of the system (rotating memory), but that company, located in Longmont, CO, I believe, may still be in business. Codar built the customized backplanes for us to use in our portable and extreme-temperature tolerant boxes, along with a few other odds & ends. I once was called upon to rectify a problem with one of their switch panels, which I did with a resistor array (a minor oversight). Dick -----Original Message----- From: Zane H.
