 The info in the following graph was generated by "SCSI Evaluator 1.01" and
clearly shows the amount of performance degradation that takes place when
my 80 Meg Quantum with the new ROMS is doing it's "exercise routines".
 The normal data was taken when the drive was acting normally, and the degraded 
data was generated while the new ROM routines were taking place. Remember that
these exercise routines occur at random times, and can sometimes go for a 
long time. NICE "FIX", HUH!!!


	View the following graph using Monaco 9 point......

 Hope we can get a REAL fix from Apple and Quantum soon!
