That's part of what makes the idea interesting. Of course I suspect you'd saturate your Q-Bus backplane with it. IIRC, the backplane can handle roughly 3MB/s. I suspect such a solution might be faster than a MicroVAX II with SCSI drives. I've not tested the theory as while PCI FDDI cards are cheap enough, the Q-Bus ones were not the last time I checked.

Theoretically FDDI should be faster, because it is capable of delivering about 12MB/s, compared to the RD* disks which might be able to deliver about 1MB/s. Kari Zane H.

I'd love to boot a MicroVAX II off of either a high end VAX or an Alpha via a FDDI link. I'm curious as to which would be faster. Running the MicroVAX II off of native disks, or over the FDDI link.
