Okay, i'm making a separate post for visibility on this -
Someone uploaded some rare light pen drivers to Google Drive, then ascended to the astral plane. The Google Drive link is now dead.
There is one wayback machine snapshot, which gives me hope that maybe, wayback machine has the files too - but the page javascript doesn't work and I can't figure out how to derive the actual content links.
just putting this out there in case anyone has done this before - is any of this stuff retrievable?
