Those are carts for the TRS-80 Color Computer, which is usually called the CoCo -- or the Tandy CoCo, since it was later issued under the Tandy name.

Some people do call it the TRS-80, but that invites confusion with the TRS-80 Model I series that often gets called "TRS-80". (The Model I was a monochrome computer that was mainly used in business environments, but had some games and was very successful in its time.)

And yeah, I was a CoCo owner as a kid, and still am. I remember it fondly. It wasn't the best gaming system since it lacked hardware sprite support or a traditional sound chip, but in the hands of a strong programmer it could do great things. Dungeons of Daggorath was the system's killer app -- a remarkable game.

Did you buy those carts? If they were all $3/cart, that's a very good price for CoCo stuff these days. I actually need all those games, too. Well, maybe not Color Scripsit.
