[HECnet] STSC APL*PLUS System for VAX VMS User's & Reference Manual

Kind reader I have two manuals labelled STSC APL*PLUS System for VAX VMS: User's Manual and Reference Manual which were sent to me a number of years ago as paper copies - I now have the ability to easily scan these into PDF format. Would these be of interest to anyone? There is a PC version archived here http://www.math.uwaterloo.ca/apl_archives/apl/apl-plus/ that might benefit from the additional documentation. I've contacted Lee about this. I am interested if anyone has any history of this software (there are some general references out there about the STSC Mainframe and later PC versions) - and indeed if the software survived at all. Was VAX/VMS APL based on this version? Regards, Mark.
