Trust me, anybody who is willing to spend $400 on a Nubus card has the time and money to hunt down the software and manuals.
I have pieced systems together that needed hard to find of rare software and eventually found it, it is part of the challenge and fun of the hobby.
To be honest if I was rich I would outbid anybody for the items I wanted, but that would also take quite a bit of fun out of the hunt. I mean bill gates can wake up tomorrow and cut a check for the most complete stamp collection on the planet ($$$$) and not even think twice about it, how much fun would that be compared to somebody who spent 40 years trying to complete his and all the stories he can tell?
