Re: CyberstormPPC SCSI question!?

The cyberstorm scsi uses a 68pin connecter.
Most LVD or SE type drives will work.  If I'm not
mistaken, the cyberstorm controller can
operate up to 40MB/s, so basically most
UltraSCSI devices or better.  I have a 9.1GB Quantum
Atlas IV which will benchmark around 30MB/s
in sync mode.  The main issue with the cyberstorm
controller is proper termination.  I recommend
using separate terminators on each end of the bus,
don't depend on a drive for termination.  The
controller itself does not have any termination.
Your bus should look something like this:

Term----CYPPC----Drive----Drive----etc..----Term.

Many ultrascsi and LVD drives do not contain any
termination, so place those devices in the middle.
If you are using any 50pin devices like most
CD-Rom drives, make sure your adapter terminates the
upper 8bits and place them closer to the end of the bus.

I hope this helps.
