Actually, I believe Data General went them one better. When the first of
the Eclipse/MV machines came out, they had the ability to execute the
instructions of the older 16-bit Eclipse machines *without going into a
compability mode*! (I think they did this be designing the MV instruction
set around the older set, so that all of the older set's opcodes remained
the same. Probably made the instruction set a bit messy... oh, well...)
Since they already had AOS running on some of the older machines,
porting their applications to the MV's consisted solely of copying the
binaries. I don't know how well this worked, either technically or as
a marketing point.
(Disclaimer: I do not and have not ever worked for DG.)
