The good news is that items lacking an internal power source (like these keyboards) are much less like to "zap" the computer than something that brings its own power to the party.
I think the most likely effect of any damage--other than "It's dead"-- would be a key that keeps repeating or one that sends the wrong letter.
Were it me, I plug these boards into the USB port on an existing board for testing. That way, the existing board may serve as a buffer between the questioned boards and the computer.
This is not based on any education--electrical stuff was not my engineering forte! Just trying to think how I'd approach it.
Actaully, I think I'd call UPS and insist they come to your house with a Mac computer and test the boards on THEIR hardware while you watch. T'would serve them right!

I think plugging into the current keyboard's USB port sounds like a fine idea, Allan! Thanks!
I was actually less worried about electrical (probably foolishly) than I was about the keyboard sending corrupted data that would "confuse" the Mac. Is that completely silly?
