Hey
@Zane Kaminski, I see there is a 16 MB option.
Niek, who created the AppleSqueezer GS, could only push it to 14 MB with an update for the GSOS for now. However, he says that it's possible to go more than that.
I was thinking 16 MB, so 8 MB is the ROM Disk while the 8 MB is memory. Could that work? Don't worry about batteries or keeping it powered o whatever. As long as it is 8 MB EEPROM and 8 MB RAM, could it work even from the memory slot in the IIGS? Imagine the IIGS automatically booting into GSOS and loading all that cool stuff fast as possible.
