Interesting...  How do the heuristics work?

Will a ~50ms slowdown work for all peripheral cards
that need 1mhz access?

if this is all that the accelerator needs to do, then
all disk II, 5.25, 3.5 drive access code must work
like this (?)  :

lda $C600  (or STA)
..
..
access disk, time with loops
..
..
..



So the access to the $C600 would tell the
CPU to slow down, and the timing loops that
access the hardware will take a maximum 
of ~50ms ?
