You can use the RCA connector to hook the IIgs up to a TV or composite
monitor, to power it up... But, from memory and my collection:
The ROM 03 is easiest to tell apart because its NVRAM battery is in a
plastic cage, and is user-replaceable. the ROM 00 and ROM 01 had
soldered-on batteries. There are differences in the board layouts as
well, but I don't have mine handy to take photos and illustrate.
Some ROM 01 boards are "stealth"; that is they have Apple IIe
connectors for power, keyboard, and LEDs to be retrofitted into an
Apple IIe's case. Other "non stealth" board has the solder pads, but
no connectors.
FWIW, if you have a ROM 00, it's only going to be good as a fast Apple
IIe. They didn't have enough memory onboard to run GS/OS, and the
ROMs didn't have the right firmware in them.
Turning it on, a ROM 00 is distinguishable because it doesn't say the
revision on the boot screen. A ROM 01 and 03 does say what it is,
when first turned on.

Subject says it all. I have a ][gs Woz Edition but I
read on the net
that there are various ROM versions. How can I tell what ROM version
I have without booting it up? I don't have the necessary additional
hardware to power it on and see the screen or type into it (no RGB
cable and no keyboard).
