Dubbed "Wicked Fast" by the Product Manager, Frank Casanova - who came to Apple from Apollo Computer in Boston, Massachusetts where the Boston term "wicked" was commonly used to define anything extreme - the system ran at a clock rate of a then-impressive 40 megahertz, had 32 KB of Level 2 cache, six NuBus slots and included a number of proprietary ASICs and coprocessors designed to speed up the machine further.
•
These I/O chips featured a pair of embedded 6502 CPUs, meaning that this Mac also had the core of two Apple II machines inside it (albeit at 10 MHz rather than the 1 MHz of the Apple II).
•
The 40 MHz speed referred to the main logic board clock (the bus), the Motorola 68030 CPU, and the computer's Motorola 68882 FPU.
