SE/30 SCSI troubleshooting

[bibilit]

I have a SE/30 not willing to boot from a good HD (and tested ok in another machine)

The SE/30 should receive a new set of caps anyway, but will this prevent a proper boot and what should i look in order to check the SCSI line ?

yeah that cap goo causes the scsi to not work.. and shorted caps also cause it as well.  so do the caps first.

after that, if it still doesn't work then you will have to get out the meter and the schematics and do some contnuity testing.

I'm not an expert but IIRC if the Mac can boot with a floppy then the SCSI chip isn't dead. It checks SCSI devices during startup and if the chip is bad then it won't display that blinking disk. It will just hang there with nothing but a pointer.

I also think the caps are to blame here. Give it a good wash and a good recap and it "should" work.

My SE/30 lost the use of SCSI. Uniserver recapped the mainboard and cleaned it and SCSI worked again. I'm not saying that this is your problem, only that it may be your problem. It is worth getting your mainboard re-capped anyway.
