CRM/6RM was a direct offshoot of the 7600 SCOPE effort.

The 7600 wouldn't be too difficult.  What I'd like to see is a STAR-100 
emulator, but that would be a very big job--and then, I don't know if 
any software is still available.  Maybe buried in a vault at Lawrence 
Livermore or NASA Langley.  Or maybe someone who kept old archives from 
ETA might have something.

Few CDCers of the time even knew that the STAR-100 existed.  I remember 
that when the initial software design briefings for the Cyber 180 were 
given that the guy describing the paging software hadn't been aware of 
the STAR doing this since 1969 or thereabouts.  I did get up and tell 
him that we'd had more experience with 64-bit paging algorithms than 
anyone else in the company and that it would behoove him to pay us a visit.

I don't think he ever did.  CDC was full of the NIH syndrome.
