You could rig up a MASSBUS-compatible controller that interfaces with either full SCSI/IDE drives or images on said drive similar to how that one museum does it. I'd love to see your -11/730 working on HECnet! I've actually had the 11/730 for about fifteen years now - I restored it out of parts from two different 730s that were scrapped. It's been fairly easy to keep running except for the drives, and although it's admittedly a bit slow, it's a cool machine.
