I just did some online searching and wasn't able to find out. I
think the easiest way to find out would be to boot a kernel on each
machine and check the dmesg. You could just use a YDL or LPPC install
CD on the G3-233 but the 7100 is NuBus so you'd need to try the
experimental NuBus kernel.

I have a spare 7200 which I can use for testing as well.
