Anybody tired SE ROMs in a Plus? Any reason not to try in terms of risking damage?
There is some software that will only run on an SE. My SEs are packed away or otherwise disassembled, so I thought I could just switch the ROMs and gain compatibility. I mean, how else could software determine it wasn't running on an SE?

My vague understanding is that SE's have some significant changes to the SCSI hardware compared to the Plus, in addition to minor tweaks everywhere else. (Including significant changes to drive the keyboard on the ADB bus.) You probably won't damage the ROMs trying (assuming they're the same chips/pinout/density) but chances are you'll just get a very unhappy frowning mac in the middle of your screen.
