Closest I got was porting an application from PDP 11/70 to VAX 11/780
(nasty job -- the /source code/ was FORTRAN-IV produced by a "C" style
pre-processor (the original application had been produced by some
contractor, but we didn't get the pre-processor, just the output).
My OS (assembly) and Pascal (UCSD) classes did make use of a CRDS
LSI-11. It had a tendency to overheat in the small room we had, with the
result that we often had to slide the cover off and aim a room fan at it.
The 8" floppy disk controller turned out to be Intel 8080 -- without the
8228 system controller chip; used a mass of 8-bit buffer/latches instead.
