Welcome back with your new forum!
Your health was worrying me, because that accident was a very bad thing! Great to know, that you can walk again!
mamebg collected all Supaplex levels from the old ThinkingGames forum at infordigital.com and created a self-extracting archive, which I am hosting on my site for the moment, together with two Supaplex documents:
http://www.hpautomation.com/Supaplex-collection.exe - mamebg's collection, unsorted with doubles, but maybe complete.
http://www.hpautomation.com/SPFIX63a.pdf - The latest SpeedFix documentation from 2007 with index and clickable links. (Please be aware, that addresses and links changed since 2007!)
http://www.hpautomation.com/Supaplex...(Improved).pdf - The original manual from the Supaplex CD, as it was meant to look like. (The keycaps font was missing from the original manual and from the CD)
