I don't remember, but it is possible that I halted the system to the
console and then rebooted without issuing an "init" at >>>. I always
wondered what good "init" at the console might do, anyway. (Not that
I knew if init resets the cache.) Fortunately there were no Machine
Checks since, and the system has been running for two days again -
with compilations, and all.

One of the two SCSI disks will be dead soon, it has already caused me
trouble. I *hope* there is no other hardware problem...
