There are some good sites for Amiga related hardware, sometimes even
with high quality photos of the hardware, driver & software download,
etc:

http://amiga.resource.cx/

Cyberstorm Mk1: CSI ID 7 Clk 40MHz CCF=8 TOut 167 NCR53C9XF(espfast)
http://amiga.resource.cx/photos/photos/cyberstorm-scsi.jpg

Cyberstorm Mk2:
http://amiga.resource.cx/exp/cyberstorm2
http://amiga.resource.cx/photos/photos/cyberstorm2-scsi.jpg

And there's even a Cyberstorm Mk3: Ultra Wide SCSI controller, NCR
53C770
http://amiga.resource.cx/exp/cyberstorm3

... and some more.

I think the main difference between CS Mk1 and Mk2 is evolution in
design and a higher integration. You'll see that the Mk2 is much smaller
in size than the Mk1.

Yes, I think there was just only one ESP driver in the past as well. So
the best would be to look at the old implementation of DMA, I think...
