What's really amazing about the MK14 design is that the original, which Clive
bought from one of his buddies, was never used. Your MK14 was in fact
designed by National Semi. They convinced Clive that it would be cheaper and
more efficient if the kit used more NS components, and they offered to
provide the design free, if he signed an exclusive contract.
