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. :) David Navas navas@sim.berkeley.edu "Excuse my ignorance, but I've been run over by my train of thought." -me
