I've bought a manual from Andrew Mick, should arrive soon. However, yesterday I spotted this: http://websd-vectrixscenecom.webs.com
Go to the "manuals (members only)" menu.
You have to join as a member, then there's a download -- I tried it but it just sat there -- I gave up after quite awhile, soo I was unable to actually download it. It would be interesting to see if it's the official manual or not.
But maybe it's a problem with my low bandwidth at home. Any one else try?
