Sorry for nosing in here in the middle of this, but...

Our local Goodwill center has acquired a number of IIgs boxes.  I have
a ROM 01 (or whatever it's called around here ;-) and would like to
have a ROM 03 (ditto) to try some tricks with the slots that are clumsy
with the 01 machines.

Anyway...  is there a reliable method to detect the ROM revision
WITHOUT turning the machine on?  They don't have power or a
IIgs-compatible monitor anywhere in sight; cheap as they are, I don't
feel like buying 10 of them and discarding the ones I don't want. ;-)

Any distinguishing marks on the ROM chip itself, the RAM or the
motherboard?
