... did a search and got Scott Mockry's page ... here's a link:

it indicates that the MAC-07 goes with a KH engine ... frankly I don't know 
a lot about the KH ... but I do happen to have a MAC-07 sitting around the 
garage.  I was looking into chipping it ... but as I recall the 
microcontroller was one with the buiult in ROM ... making it difficult to 
"chip" a la QLCC ...

I've got to believe that the KH has got most of the improvements ... as the 
WX engine in the urq has them ... of course a quick check of TFA should be 
able to make this certain ...
