Is it a rarity? > Etc. > I'd figure after typewriters, fililing cabinets, desks, etc., commodore went into the adding machine business (as I have seen a few C= models for sale) and then when calculators hit it big they bought chips from Texas Instruments (TI) not too long after buying some huge order TI decided to get in the calculator market with using own chips and way undercut all the people they sold chips too. Tramiel at that point didn't want to be burned again by such tactics bought a chipmaker (MOS Technologies), owners of the 6502 and ran by Chuck Peddle, which helped pave the way to making the PET and other computers.
