I heard that redoing the NMOS designs into CMOS was the sole reason CBM 
helped Bill Mensch set up WDC.  Bill mentioned it to me in the mid-90's 
when I interviewed him for Commodore World magazine.  I remember it 
because Bill chuckled on the phone and noted that he was one of the few 
people get money from Jack (so it must have happened prior to Jack 
leaving for Atari).  I asked for details, and he noted that CBM set him 
up (probably gave him seed money in exchange for CMOS design help or 
stock in the firm, not sure about that part).
