[Elecraft] Update on a Question About the P3 SVGA and Mac Computers

[tom armour]

Why not just look at the P3 display?  Don't you need that to have the P3 SVGA?  I don't have a P3.
What about using a Softrock Lite IF to a USB sound card on the Macbook Air?  The Softrock Lite is about $22 but you have to build it.  You could also get a LP-Pan2, but you already have the P3 so you may not want to do that. 
A quick google search turned up this:http://www.epiphan.com/products/frame-grabbers/vga2usb/
It is $299 list price, but there should be other less expensive vga-to-usb devices that can be used on a Mac.
Hope that gives you a place to start.  Although I may not be understanding what you are asking al.  I do have a Softrock light IF to a sound card on my Windows PC.  I have not tried it to my Macbook Pro, but that is a company machine.
