I'm confused:  What's the other direction, other than away from the
SCSI card?

Easy:  there are no special drivers for the 3rd-party SCSI cards
because their manufacturers haven't written them yet.  There isn't
an _extreme_ need for them, although efficiency will presumably be
improved by using a "loaded driver" instead of letting GS/OS use a
"generated driver" that uses the 8-bit ProDOS interface on the card.
(Efficiency of Apple's SCSI.DRIVER will also be improved in the
future--right now we have only an "interim" driver that _works_ but
isn't as fast as the real one will be.)

Ask Claris; I don't know if they're selling Deskworks now or what.
(StyleWare used to.)  BTW, it isn't an NDA, is it?  (NDAs show up
under the Apple menu.)

No, the thermometer is driven by a 1/60-second interrupt routine,
and it starts early in the boot when START.GS.OS is loaded.  I
believe your SCSI card is leaving interrupts disabled for a large
fraction of the time during the boot.  This is not a problem, except
that it means the thermometer will do what it does rather than what
it should.
