The Fireball series doesn't work at all with a RamFast.  My theory was
that the Fireball requires that the host supports the arbitration phase
(and have its own SCSI ID), and the RamFast doesn't do this.

I have a TrailBlazer, and I believe they work on a RamFast.  The
TrailBlazer is a slightly older series than the Fireball.  I expect that
all series newer than the Fireball will use the same architecture, and
will therefore be completely incompatible with the RamFast.

All of them should work fine on an Apple original or High-Speed SCSI
card (my TrailBlazer is on an Apple HS SCSI card, and has been used with
an original Apple card, and I think I've had it connected to a RamFast
once).
