IF this works then OLD snapshot wil not function at all by MIS placing HALF a register pair. so then the 'new' snapshot has to adapt after 35 years ??
hmm
I've noodled on this bug for a while too, and came to the conclusion its not worth fixing.
Any 128 snapshots I have done with the bug work, whilst i know they aren't technically correct, the software that is snapped usually functions.
It does raise the question of how 128K snaps on the plusD would work on the disciple... (they do)
Actually, looking at this, I don't think it will break old snapshots... they will still work.
I think they end up with wrong values in A'F', but they have that today anyway ?
Maybe GDOS 3E is due
