Motorola
From Sega Retro
Motorola started as Galvin Manufacturing Corporation in 1928. The name of the company was changed to Motorola in 1947, but the word had been used as a trademark since the 1930s. The company is based in Schaumburg, Illinois, a Chicago suburb.
Best known for manufacturing mobile phones, Motorola also produces microprocessors, including the 68000 (Sega Megadrive) chip and the 6502 (NES).
Motorola's microprocessor division is now known as Freescale Semiconductor and can be accessed from the link below.
