Good work with the hardware hack, John!

Was this with the pal in or out?   No, I haven't ever seen this error.

I'd certainly say so!  (Unless CT can somehow prove that you used
privileged proprietary information, in which case your posting is a big
no-no, because you gave away the info to the world.)  I'd say it's
practically spelled out in the .h files and schematics anyway; it's
just that nobody ever *knew* it would really work.

Although I like the drive select hack, and I will investigate the idea,
it doesn't decrease my craving for SCSI at all.  And I'd gladly pay more
than $350 for the SCSI board if it really existed and had software
support for some things I want to use it for.
