 MITS had announced a new computer based on the Motorola 6800 microprocessor in November 1975, the Altair 680. The machines were supposed to ship in January 1976, but hardware design problems delayed shipment until May. Paul Allen rewrote their 8080 simulator to support the 6800 microprocessor. Ric Weiland, a high school friend of Gates and Allen, converted the Altair BASIC's 8080 assembly language to 6800 assembly language. To eliminate the per copy royalty loss issue, the 6800 BASIC was licensed to MITS on a non-exclusive basis for a flat fee of $ 31,200. Weiland and Marc McDonald were impressed with the new MOS Technology 6502 microprocessor that was a derivative of the 6800. They modified the 6800 development system to support the 6502 and "cranked out" a 6502 edition of BASIC. This version was later sold to Commodore and Apple.
