Yes, it also has narrow SCSI-2 built-in (though the boot PROM doesn't
understand synch negotiation, so any device that you want to boot
from must not start synchronous negotiation by itself).

And yes, the FWSCSI bus (that's how HP labeled it) in this machine
is high-voltage differential (the only differential scheme at the time;
the LVD drives did not exist back then). I know; I have a micropolis
3243WD and two Seagate ST410800WD in mine.
