Motorola 68030

A 32-bit microprocessor in Motorola's Motorola 68000 family, with on-chip split instruction and data cache of 256 bytes each. The 68030 has an on-chip MMU (except in the 680EC30 version).

The 68881 and the faster 68882 FPU chips could be used with the 68030.

The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040.

The 68030 is used in many models of the Apple Macintosh II series of personal computers.

(Macs powered by the Motorola 68030 processor cost less than comparably equipped 80386-powered computers.) These computers in libraries are probably being replaced at the low-end and midrange -- as in business demonstrated by the IDC audit -- by Macintosh Classic and Performa models, and at the high-end by Centris and Quadra models (see Table 3 and Figure 1).
Processor boards hold four Motorola 68030 user-processors, each with a floating point accelerator, 4 Mb of program memory, and a special-purpose processor that ensures all user processors have a common view of and simultaneous access to the PIM data memory.
