Not necessarily. There's value in preserving objects even if they are not in
runnable condition. Yes, having runnable system as LCM set out to do is
interesting. It may also involve compromises, such as replacing failed
original modules by replacements that are very different. You can see this at
work in the LCM CDC 6500, where a number of the 4k x 12 core memory modules
were replaced by SRAM based replacements. They are easy to spot in the photos.
They would probably operate differently too -- SRAM doesn't change to zero
when read, and that actually creates a user-visible difference in the case of
PP memory.
