>it’s a museum; of course it’s read-only memory!
What, they never acquire any new exhibits?
>ROM doesn’t actually mean that the memory can’t be written at all;
Doesn’t it mean exactly that, in the context of the computer it’s part of? Maybe it got written in some factory, but the computer it is in has no way at all to write to it. If we let go the stipulation that a memory’s situation in a computer is its defining context, then wouldn’t we have to include even memories that had not yet been invented, and all sorts of other pathalogical cases?
