After many tries, I finally did get the SCSI-2 docs (I don't think I
went to the above site, though...)

Now all I need to do is get to the reading part and doing a few
bread-board designs. Always has helped me to work up "simple"
bread-boards to understand spec concepts.

Ah! Thanks for the info on AMD... I was not aware that they make SCSI
chips. I have some info now from National, TI, and a couple of others
and info on the way from NCR.

Actually, the software is the least of my worries... I will probably
do the code for the actual driver(s) in assembler for speed/code size
concerns. Besides that, I'm old fashioned that way.  ;-)

There will be at least level of user interface as well and I will
probably do that in Gnu C++ simply because I have a lot of objects
already written that will make the process nearly a plug and play
programming task. No sense in reinventing the wheel!
