Bombed SE

[bibilit]

I have at home a bombed SE with checkerboard.

A pair of traces have been repaired, but still having the issue.

Are the Bourne filters required in the boot process ? apparently i have no reset and filters are close to the battery and also close to the reste switch.

Answer for myself, never look only at the damaged area, look around also.

After testing only the bombed area, i started poking around, and one trace was looking bad… and was broken, near the CPU !

A quick patch and the checkerboard was gone and i got a chime and flashing floppy.

Was even able to boot from a floppy, still have and issue with the SCSI, but far better.

The SE is a beast.

The metal brace is gone for good, replaced with another though.

Another broken trace under the SCSI chip and the bourne filter !

A quick patch and the SE is fixed.

Nice troubleshooting! That brace is gnarly, it must have been ugly in that machine beforehand.

Thanks.
Yes, was crumbling apart, had a worse SE/30 board to remove the part from.
