[Coco] Possibly fun Rainbow trivia - can you guess the application?

[John Guin]

Hello all,

I was updating some of the OCR results for the Rainbow magazine scans at http://cocomag.dyndns.org/TheRainbow.shtml.  One of the tasks was to second check this text:

"When you use this program, your players will not have to be told room sizes. They will be able to estimate,just like real life, because the rooms are to scale, and the doors are known to take up 10' of wall space. This way, there is no need to give away information. If the players want to know exactly how large a room really is, let them buy a measure and take the time to use it! By the way, because the pixels on the color computer screen are not exactly square, a square room will appear on the screen to be slightly higher than wide. If that causes any estimating problems, attribute it to the poor light."

This really caught my eye since it seems very unusual for the Coco.

I thought it might be kind of fun to have interested folks guess at what might have been going on with this article.  What kind of app was being run?

No fair looking it up until after you guess!

So anyone want to take a shot?

John
