I have a game called "orbit". The README says "This should work with no changes on Berkeley 4.2". The graphics seem to be raster bitmaps. I see references to "sun", and not as a star. There is 68000 assembly code in it. Timestamps are August 22, 1983. I don't suppose there's a 4.2BSD for a Sun workstation?

SunOS 2.0 and 3.0 are 4.2 from what I recall. And they most certainly use the 68000 instruction set. They would be the most likely target.
