 Other prototypes which never made it to market include the 1600XL, 1650XLD, and 1850XLD.The 1600XL was to have been a dual-processor model capable of running 6502 and 80186 code, while the 1650XLD was a similar machine in the 1450XLD case.These were canceled when James J. Morgan became CEO and wanted Atari to return to its video game roots.
