ComputerVoltageSources

After all, if you are going to add USB, why not just make a USB to 8 x 0 to 10 volt inputs and 
outputs. Get or steal a driver, and scr*w the Basic Atom Pro?

Actually, they probably make LabView interfaces just like that, possibly with interface drivers 
already written for C-Sound.

All of which makes this WHOLE thing silly, unless we can get a board for $50 that a high 
school student could build as a science fair project (or Dad).

A "modern" implementation is several quantum steps from a PSIM like device.
