Indeed!

The same people advertise 40MHz CPUs as being 80MHz (which they are internally).

To make a CPU in a 575 run at 40MHz, as in most (all?) computers you have to change the speed of the clock signals supplied to the CPU by the logic board.

For the 575, full details are at:

I was in the fortunate situation of buying a Mystic with the work already done.

Chris has / is about to make up some clocking kits to get ecomonies of ordering scale for people, but I understand that he may be off-line (or only intermittently on-line) until the New Year.
