No, the hardware failure is that the machine's SCSI controller seems
to be fried, thus internal drives no longer accessible.  I have a
working NetBSD-current installation on an external USB drive, and plan
to commission it as a buildfarm animal once NetBSD 10 is officially
branched.  It'll be a frankencritter of the first order, because
USB didn't exist when the machine was built, but hey...
