Pictured here is one of the first computer’s I ever used, a TRS-80 Model 1. It came with either 1K or 4K of RAM, and for “sound” we put an AM radio next to the monitor. (The RFI squeals and hums were only somewhat synchronized to the action on the screen.)
You can’t really tell, but the program running on this one is a version of “Star Trek.” It’s probably hard to believe in this day and age, but that game could get pretty intense if you happened to warp into a sector with 3 or 4 Klingons. A lot was left to the imagination, needless to say.
