Since it's a BASIC listing and there's some intrinsic educational value in being distributed in source code form, we believe our distribution of it falls under fair use.
I already had the source, but over time I've acquired an IP conscience that wouldn't let me go as far as you've gone. (Seeing Charlie Anderson explain to me stuff about his program that I would have known had I not been using a pirated copy was a wakeup call, even though he was far from his $1000 and 10% days.) But perhaps when software is 30+ years old, it is better to seek forgiveness than ask permission.
Is there any way to contribute to Discorunner? It seemed kind of resource intensive when I last used it, and wanted to look at source to see if I could help, but I didn't see any way to contribute.
