+ | The X68000 Super is the last and newest of the original 10MHz 68000 machines. It was superceded by the XVI & XVI Compact running at 16MHz and the X68030 & X68030 Compact models with their 68030 processor. Unlike previous 10MHz models (the X68000, Ace, Pro and Expert) it has proper SCSI-1 bus support and 2MB of RAM onboard, rather than the earlier (and slightly incompatible) SASI bus just 1MB (though all those machines could be upgraded to 2MB). | ||
