>Can an AppleCD 600e fry an SE/30 system board? > Only if the SCSI-related parts are very, very kaputt (sort of short-circuited), but it takes a lot to fry a whole mobo via the SCSI port, the risk is in the SCSI chip. Sounds more like you do have a hardware problem, but not the bellyup kind, to follow the Macquarium picture. I suppose you did all the usual SCSI voodoo; your internal HD must have been terminated, else it wouldn't have worked before; did you verify the terminator on the external CD is not flakey? I understand your attempts to get the Mac working again were *without* the external CD, right? If else, does the machine work with a different, properly terminated external SCSI device attached? What does the Mac do with the internal SCSI cable removed from the HD if you try to start from floppy? HDs (and cables as well, had this in a IIvx) can go bad, and Murphy's law says they'll do it when least exspected.
If all this doesn't get you further, you can still try to at least confirm your suspicion about a fried mobo by swapping it with your second SE/30's. You don't have to risk it by hooking the external CD to it, but you can hook it to a less valuable machine to test it (BTW, did the Cube have SCSI? ;-)) >I have an SE/30 128MB, 1G hard drive, internal Ethernet card that has been >sitting idle for some time, which I was considering loading with NetBSD.

The system did not recognize the CD drive Sometimes Macs get confused about removeable media drives when the appropriate drivers aren't there or when there are multiple removeable media drives (e.g. CD-ROMs and Syquests).

Don't give up on the board. Keep us posted about your progress. Just out of curiosity: My SE/30 128/1G takes about three minutes to check the RAM when starting up. How long does yours take, and is this different when starting up from floppy? (I know it shouldn't, but you never know...)
