The spelling quizzer is a very simple, text-based program that should run on any PC. Just download the file to your desktop and double-click on it.
Right now the program quizzes scales, intervals, triads, seventh-chords, diatonic triads, and diatonic seventh-chords.
Though the text interface may initially appear very crude and "unmusical," I think this program has a few strengths.
Sept '08: I was getting reports that the old interface wasn't working with Windows Vista. This new one (version 2.3) should be fine.
Have fun, happy studying!
