I forget if V7
needed I&D space or 2.11 meaning the 11/23 was not enough.
The 11/73 has the added I&D bits where 11/23 only has user registers and
MMU.
BSD2.11 does need separate I&D, but V7 doesn't. If you don't have separate
I&D, ISTR you need to build it for "small machine", and it runs a bit
slower. I tried swapping my M8186 (11/23) for M8192 (11/73)
but it doesn't run.
Maybe I need to rebuild the kernel (I've got an original distribution, not
one of the images from PUPS), but perhaps it would work with more memory or
by swapping RLV11 for RLV12.
Cpu doesn't run or doesn't run V7? The image I have only wants some 256k
of ram out of all teh installed ram. I get the impression it was
configured for an 11/34 or similar and that is mostly a 11/23 save for the
11/23 mmu can go to 22 bits.
