The hard drives I have are Quantum 105s 3-1/2 full hight drives. I would 
have to guess from about 89 to 91?  One of the first generation of scsi 
drives with imbedded controller.  Also, I got Nitros9 6309 working, and 
mega read is identical to my original os9 system.  See below:

Scsisys 1.1 driver used on all versions of os9, and same megaread used also.

Stock OS:        31 sec
Nitros9 6809:   31 sec
Nitros9 6309:   36 sec

Not sure why, but the 6309 version is the slowest.  using same exact 
hardware and scsi drivers.

Also, I have not been able to get any serial port drivers or parallel 
port drivers for the disto 4in1 to work.  So, until then, I will be 
staying with the old system.
