You (Chuck) and Dave are speaking specifically of so

mechanism to default to a batch of code in a rom address is news to me
though, even in a hundred percenter. But since there is so much
compatibility amongst BASICS, as was mentioned recently, and given an
empty socket (curious to know which mobos had them, probably few if
any) or a board that would extend an existing socket, is it likely an
IBM chip would work, even if you had to manually transfer execution.
I take "clone" at its face value the same way as I view "pregnant".
You either are or you're something else. An Eagle 1600 runs MS-DOS
but is not a PC clone.
But I don't follow the rest of your post--perhaps if you used shorter
sentences...
