From what I understand, some of the new code in the ROM
03 is needed to
run some applications, and the GS/OS (the GUI OS for the GS as compared
to ProDOS)
I'm able to run System 6.0.1 (I assume this is what you're referring to as GS/OS)
on ROM 01 systems (I don't have a ROM 03 system, only ROM 01's and maybe a Woz).
