Was lucky enough to have a sit-down cabinet version of Star Trek: Strategic Operations Simulator (Sega, 1983) at a local arcade. Very comfortable with the controls built into the chair. Along with having set all the games to free play, the operator had the volume cranked on this one so Nimoy’s voice would resonate inside!
Agree with the other respondent; that Goodwill store is the best one I’ve ever been to! Hopefully you also got an A520 modulator with the computer, else you might be limited to the black-and-white composite video signal out the computer’s RCA jack. Tough/expensive to find a display compatible with the 15KHz RGB signal out the 23-pin connector.
