Eugene,

  There is currently only the 8bit Single Ended version of SCSI Host Adapter
for the TURBOchannel. There are further developments coming both from Third
Parties and from DEC. You are far more likely to see FAST DIFFERENTIAL SCSI
before you see FAST WIDE DIFFERENTIAL SCSI and I don't currently know of any
development for 16bit SCSI that is being considered that is not also using
differential signalling (meaning you would require a differentially signalled
storage device). 

   NOTE: To my own usage	Standard SCSI  =  8bit
				WIDE SCSI      = 16bit
				VERY WIDE SCSI = 32bit

Just to avoid any confusion as to what I said...

  If you would like, I can pass your name along to the Third party involved
and see if they are willing to talk to you in advance?

I hope that helps.

				Thanx,
				  AJ
