SCSI yes. Q-bus no. Get real. No one is going to produce cards for this
beast since the market is so small. You are going to have to use a commodity
bus such as PCI to get peripherals. If Compaq were to make a new VAX, you
can be use it would be PCI based with no ISA.

Q-Bus is asynchronous bus. There is little or no timing. That makes it
hard to speed up.
