Fair enough! Thinking about it a bit further, he has more avenues to release what he had - assuming he still has anything - to the community today than he had 20 years ago.
Maybe things have settled down for him a bit since then.
It looks like he's still a mathematics instructor in Minnesota. I won't link to it here, but it's pretty easy to track down his contact info online if anyone wants to reach out to him and see if he still has any of the original materials available.
