I never owned a TRS-80, but my high school had a Model 16 running Microsoft Xenix with maybe 10 serial terminals attached to it. (This replaced a small Burroughs machine and card punch.) The business department ran COBOL classes on it. The COBOL was forgettable for me but it was my first *nix and got me started using vi (and writing stuff to other users' ttys). Pretty amazing that it could handle that.
