How many Apple II CPUS's did the new Macintosh llfx include?
With the new Motorola 68030 processor came the Macintosh IIx in 1988, which had benefited from internal improvements, including an on-board MMU. It was followed in 1989 by the Macintosh IIcx, a more compact version with fewer slots  and a version of the Mac SE powered by the 16 MHz 68030, the Macintosh SE/30. Later that year, the Macintosh IIci, running at 25 MHz, was the first Mac to be "32-bit clean." This allowed it to natively support more than 8 MB of RAM, unlike its predecessors, which had "32-bit dirty" ROMs (8 of the 32 bits available for addressing were used for OS-level flags). System 7 was the first Macintosh operating system to support 32-bit addressing. The following year, the Macintosh IIfx, starting at US$9,900, was unveiled. Apart from its fast 40 MHz 68030 processor, it had significant internal architectural improvements, including faster memory and two Apple II CPUs (6502s) dedicated to I/O processing.
