Yes, you're right...it's a ROM 01 machine.

Problem #2.  I downloaded the GS/OS disk images onto a Powermac  and used
Disk Copy to make 800k floppies out of them.  When I try and boot from the
first one, it tells me "UNABLE TO LOAD PRODOS."  Any idea what might be
wrong here?

I'm not that familiar with either ProDOS or GS/OS, is there any kind of key
I can hold down during startup that would let the machine boot without
extensions or into some kind of a safe mode?
