If you check the following link you'll find a plethora of Apple II emulators for Mac OSX.

Similar should be available on the Windows platform. Wouldn't these allow you to run BASIC software without buying old hardware?
I had the great fortune of first self-learning programming (in the early 80s) by playing around with simple programs. In my case the tools was HyperCard, whose HyperText language is very similar to BASIC. In fact HyperCard still runs on my Mac (OSX 10.3.9) under the Mac Classic emulator, even though the software is probably 12 years old now.
Thanks for the interesting article.
