So is it safe to assume that I would need to start with these patches first,
maybe followed up by a good midnight reading of the NCR 53C700/53C700-66 SCSI
I/O Processor Data Manual to put the lookup tables in place. I am also
assuming that I can only get this from the phone numbers that you listed in the
code.

The system has this as the built in board and no real way to diable it (kind of
dedicated PC box for backup), so this is not an option.
I assume that the 53c8xx_d.h is newer than the 53c7,8xx.scr since it looks
like the code is "fixed up whenever the nexus changes so it can point to the
correct routine for that command."
Otherwise it looks like the majority of the code is basically there (albeit
from the notes not tested).
PS the NCR53c8xx.o mod looks like it might work but the fork that I try to load
it in hangs. I am working on getting more information and hopefully a core
dump (although I have not figured out if this is possible for modules yet or
not)
Thanks for the pointers, looks like you had a blast figuring this thing out.
