 In late 1976, CBM, quoted at US$60 million on the NYSE, purchased MOS, valued at around US$12 million, in exchange for a 9.4 percent equity stake in CBM in an outright buy on the condition that Chuck Peddle would join Commodore as chief engineer.The deal went through, and while the firm basically became Commodore's production arm, they continued using the name MOS for some time so that manuals would not have to be reprinted.After a while MOS became the Commodore Semiconductor Group (CSG).
