Correct me if I'm wrong, but I thought that you had to synchronize with the
CHIP memory for every access request....  That might explain it.
[CHIP RAM accessed by chip memory at 7Mhz, and while the A3000 looks at that
 memory as 32 bit, I thought it could only look at it at that speed?]

or it could be bad luck.  :)
