Well, I just spoke with Brian McGhie (who's some sort of boss around the toolbox group:-) and according to him, System 6.0 is not supported on the Mac 512Ke. The reasons included some real hardware differences between it and the Plus, address lines brought to the ROM are different, the clock chip has more parameter ram, and serial chip addressing is different.
