Here's my map of the old Traveller setting from Judge's Guild. If you click on it you should be able to read the labels on the full-size version.
Back in the 80's the Guild published something like ten modules for this setting. I'm still trying to determine if additional information appeared in any of the various JG periodicals.
One of the fun things about this setting is that several of the polities are on the brink of a fullscale interstellar war. But unlike the 5th Frontier War I'm pretty sure that no official version of events outlines the course of the war.
