Commodore was into calculators before moving into computers. In the early 70s they got their chips from Texas Instruments, but when TI decided to start selling their own calculators, which were cheaper than Commodore’s it initiated the “Calculator Wars”.

Not mine but guy who has this found it in trash can. Check the garbage!
