008- I just reinstalled System 6.0.1. Now every time I
cold boot I get this message 'RamFAST/SCSI is searching
the SCSI bus for devices' and have to wait several
seconds. WEIRD?!
When you reinstalled the software, the RamFAST set itself for a long
search. This is an option that you can change using the RamFAST utility. What it
is doing is giving your scsi devices a chance to spin up. If you want a fast
check, go to the options menu on the utilities and reset the Short Timeout
option there to "YES".

009- I would like to make my own SCSI cable. Does anyone
on csa2 know the pinout for the standard 50-pin SCSI
cable?
The cable pinout is documented in the technical reference manual for the
Apple High-Speed SCSI card (and the original one as well).
This pinout is not a simple mapping from one end to the other; it is NOT
easy to make one of these yourself. Apart from any issues of wiring errors, you
also need a properly shielded cable to minimise noise being picked up or
radiated. You should definitely not use a ribbon cable.
Here is the pinout, assuming I haven't made any typos (I can't see any).
