@Al Kossow, I tracked Curt Vendel's Mindset hardware and software directly to the CHM. He had everything that ever existed, including all the development software, and it is now in the CHM collections.
This is highly problematic, because that means it's in the warehouse, and the warehouse is literally like the ending scene in Raiders of the Lost Ark. This means, it will never again see the light of day, unless some billionaire decides he wants to look at it.
(Sorry, I have _very_ bitter feelings toward the CHM and the way they treat many of the things they've curated.)
