Any idea who might have a copy of the modifications to the V6 source to
support RL02's? It'd be wonderful to put that into the PUPS archive.

This particular V6 system is indeed a very nice environment for someone
with a "small" 11/23 and RL02 drives.

That particular 11/23 system from UBC was used in the biology department,
judging by the non-system files found on the "user" disk.
