Oh wow, I was thinking of writing a very similar post too. Denthor's tutorials were one of my first introductions to programming, and I too fondly remember typing them all into Turbo Pascal and trying to understand exactly what they did. I've always wondered what Denthor / Grant Smith was up to in the years after the tutorials, and if he ever thought about how many people he might have helped get interested in programming.
I also searched around a bit and found this good thread that seems to indicate Denthor is doing well these days and lives in England with a family: http://www.pouet.net/topic.php?which=7530&page=1
If anyone's curious you can actually find Denthor's tutorials here: http://textfiles.com/programming/astrainer.txt
