My first FS experience was on an Apple II, then later my lowly C64, and MSFS 1.0 on the best PC we could find on campus (late at night, naturally). I've been programming professionally for almost 30 years, and tinkering for over 40. In the last decade or so I've really come to appreciate open-source software, from both a user and creator perspective and try to support that model as much as I can. All my open-source projects are hosted at GitHub. Cheers!
