Other way around, I think. It was originally designed by SMS.
The basic machine clocked at 150nS and completed an
instruction every 250 nS (really!).
125 ns and 250 ns. In other words, 8 MHz maximum with two clocks per
instruction cycle, for a 4 MHz instruction rate. Much faster than any
other production single chip microprocessor in 1977.
