Doesn't the ROM dump the RAM size into a low-mem global or does it only 
give you up to a certain size?

I'm not sure about the SE/30 but I think most machines have a 
pseudo-NuBus ROM at the end of the ROM space that describes the 
machine. At least, some of the machines do.

I also seem to recall there was an older ROM-based API that identified 
a machine as Plus, SE, SE/30, Mac II, or "Other". Perhaps the code can 
check for the pseudo-NuBus ROM if it gets "Other".

I think you can get some of this info from low-mem globals or ROM calls.

In theory, shouldn't it be possible to put this image into a fake HFS 
partition?

This is very cool!
