Well, they wouldn't compare exactly- the microcode ROM sets
are serialized...

But when I disconnecte the cabinet airflow sensor, I
get an error message displayed that's not in the
VCP's Z-80 boot ROM, but is only in the microcode
ROMs. Now, whether the Z-80 is retrieving and displaying
that message, or the microcode is getting loaded and
the Prime CPU is issuing the message, who can tell?
