That is copied from a PM to another member here.VistaTek had several different revisions before the company went bankrupt, and being that it was in 1998, there is very little concrete information on the internet to help. But by looking around, I have narrowed it down to one of these:

http://www.mindflux.com.au/products/keo/xl50.html" onclick="window.open(this.href);return false;
http://www.mindflux.com.au/products/keo/xl35.html" onclick="window.open(this.href);return false;
The XL35 and XL50 are both much higher resolution, the only difference is the field of view. Which is actually pretty impressive, considering how far away those modules are from the eye! I think the XL50 would probably be using optics that are 60 FOV, but is reduced by the eye distance. And apparently, gauging from the marketing literature, the color gamut and contrast ratio is excellent, here is a page with some pictures: http://en.souvr.com/product/200712/189.html" onclick="window.open(this.href);return false;
The PV60 also looks impressive, but less so. Vista Technologies appears to have used both a 640x480 and an XGA resolution revision, but I cannot be sure.
I found a set of two ProView HMDs, but I cannot figure out which one of those it is. They all have dual VGA and S-Video inputs via the control box, though.
I found someone selling two of these in a set through a liquidator, they are not very informed on what they are, exactly. I can get both of them for $1,900! Possibly less, if I can negotiate down a bit. Is anyone out there interested in buying the set with me? We would split the costs, and each get a very, very nice HMD. The entire line has excellent contrast and color compared to other HMDs.
Considering the price of even a V6, which has much lower quality LCDs, around $1000 for ANY of the ProView line is an absolute steal. And for reference, the XL50 goes for $27,000 new.
I am not going to post where I found these, and if you have found them independently, probably best to not post. I would hate for some random lurker to find them, buy them, and then a valuable opportunity to learn about high end HMDs be lost to us. An interesting note is that the ProView lines uses direct view optics, not folded, and use rectangular optics, yet achieve very high FOVs.
Anybody have any comments/speculation/identification help/interest?
If anyone wants to see where these are, PM me, I would be glad to link.
