I searched long and hard to find a game called "Empire" (based on Hammurabi) for TRS-80, and finally found it as part of a CLOAD cassette tape dump on TRS-80.com. Fired up an emulator and was instantly transported back to elementary school computer class in 1986... fun times...
Also rediscovered an old DOS game called "The Wizard's Castle" which I originally played on a DEC Rainbow 100 running MS-DOS 2.11.

I recently found the original program online and it works perfectly fine on XP.
