[Coco] megaread HOW TO ?

[Mark Marlette]

Charlie,


SuperIDE was not optimal for CoCo transfers, but was still very good. TC^3 had xfer rates for mega read around 9-11 seconds depending on the drive. I have not yet benchmarked the new interface with SCSI....yet


You out to see what the new transfer rates are on the the prototype ;)

Thanks so I used:  date -t ; megaread < @/dd ; date -t
        to find that my SuperIDE had a MegaRead of 17 Seconds.

Replaceing @/dd with @/x0  I found that the
        JAVA drivewire server had a  MegaRead of 18 Seconds and the
        PYTHON drivewire server had a  MegaRead of 20 Seconds, this
        is through a USB port and with a 115200 baud rate.

I was surprised the Hard drive was not faster.
