this caught me by surprise:
http://serverfault.com/questions/470126/how-can-i-successfully-mount-an-8-bit-scsi-drive-on-a-modern-computerAs the comments on that page mention it is trivial to image NeXT SCSI drives, so that should not be a problem - it would be very interesting though to see the environment snapshot as a particularly interesting use of the NeXT development environment.
This is awesome.
I'd love to see it!
