Thanks for the help Soundog and Psarkissian. With your links, Soundog, I was able to get it to work on my Mac. Now I just need the USB interphase. :) l'll be looking for one of those as soon as I send this message. :)
In other news, my kids, who have been playing for years, couldn't put the VaxAC700 down when they came over last night. I've got the tone pretty well dialed in with my system, and they just couldn't get over how great they sounded playing it. I've got a great collection of guitars... including a older Les Paul and Martin D15, along with a Strat, Dean, and even a handmade boutique acoustic, but they just wanted to play the Variax. What a great guitar. Now the kids are on ebay, craigslist and reverb.com looking for one of their own.
Having said all of that, do you have any idea on why they were discontinued after such a short run Psarkissian? (That is if you are allowed to say.) I see how the tech advanced into the electrics, but the acoustic look and vibe of the VaxAC700 is just too cool. Any plans on reviving it?
