MX
- n. Originally the designation for the micro-coded controller architecture that succeeded the LC2. The product was renamed LX when it went to market, possibly because of the MX peacekeeper missile that was in the press at the time. The MX controller was first demonstrated driving a low-cost laser imagesetter. After the LX had been selling for some time, the MX moniker was revived to refer to the Macintosh product based on the same architecture.
