Hallo Nick,

I just looked up the old Big-C project where I intended to use a 4 MHz
65816. The idea was simple: the moment a "slowdown" was detected, the
processor was forced to wait 4 whole cycles plus the one it was in at that

I will send you a gif and the according text that goes with it in private.
The slowdown circuit covers the top part of the SCH.

Ah, then I'm not the only one anymore :)
