Can someone help verify that this ROM works in an SE/30? If I made the changes correctly, it should have the checksum test removed and also skip the RAM test while booting. I figured I could just test it in an emulator before buying a ROM SIMM that had this on it, but no emulators seem to exist for the SE/30, IIx, or IIcx. I really want to avoid having to buy the ROM programmer if I can avoid it.
