El Reg has a write-up on the amazingly beautiful and hopelessly impractical Honeywell Kitchen Computer. We've covered this bizarre piece of computing history before on OSNews, in my list of the ten most beautiful computers. For those that have no idea what I'm talking about, read on for more details. Trust me, you want to know.

The 1.6 microsecond memory timing referenced in the brochure suggests the 0.6MHz figure. (1.6µs translates to 625KHz) Remember, no cache. If it did run at 2.5MHz, it ran at an *effective* 0.6MHz.
Adequate for most 1960s kitchen computing workloads. The complimentary programming course and bundled Shish-kabuntu were a nice touch, too. "
Note that 625 kHz x 4 = 2.5 MHz. Many CPUs used to require multiple clock cycles to execute instructions. That was the difference between a clock cycle and a machine cycle.
