Vague Memories
I spent many happy hours watching a Mac restart after some system error in the early 1990's.
My memories are pretty vague, but I thought we used System Software version 7 at the time, but we had colour monitors, so maybe it was a later version.
We ran Photoshop V2 (I think) but not well, and no-one really enjoyed it.
Even though it was all pretty slow, it was obviously going to get better and the noble trade of Photolithography was on the way out.
