It's actually the old text-based Star Trek game. If you zoom in on the picture, you can read: "Objective: Destroy __ Klingons in __ turns" (I can't make out the numbers) and "The number of Starbases is 7." The grid on the left that looks like a memory dump is actually a map showing the relative locations of the Enterprise, Klingons, stars, and Starbases.
We played similar games on the pdp8. You had a limited number of Photon torpedoes, limited energy split between shields, sensors, phasers, engine power and life support systems.
You had to enter coordinates for torpedoes. Phasers just blasted stuff. If your warp engines get damaged or you lose too much energy, impule power only. Star bases can be used to repair and refuel.
Yep, Star Trek game. Real popular back then. I bought my 1977 Apple II and it came bundled with Star Trek on cassette tape, the only way to automatically load it without hand-typing in the program code. My Apple II still works, although I upgraded it to run on USB memory sticks with thousands of programs, and I will still play Star Trek as a nostalgic remembrance of the past from time to time. The PET, TRS-80 and Apple-II came out around the same time, a step up from the Altair and IMSAI machines out earlier, in ease of use.
