Ah... they must have been recycling old 6530s rather than making
new ones. That's handy to know (I have a few DOS 1 6530s from
the bench of the former local C= dealer that came out of 2040s
that were upgraded to 4040s; likewise, I have no "4040s", just
upgraded 2040s).

I also have a wide variety of original C= service manuals (from that
same defunct dealer). I might have the 8250 manual, but I'm sure
Tony is correct - the flash codes should be the same.
