  I started on an MK14. It took me many years to figure
out that darn 
  manual. And the hardware design was somewhat clueless (hint : A 74157 is 
  a multiplexer. A 74175 is a latch. Using the former as a latch is 
  possible, but not a good idea if you want to avoid timing problems. Guess 
  what this machine did...) 
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.
