In 2023, many people use two or more monitors on their computer to increase productivity. It is generally thought that Apple introduced this capability to personal computers back in 1987 with the release of the Mac II. It appears that someone else beat them to the punch with a way to do it on the non-expandable Macintosh Plus, and I got it working again.
