I have a Wallstreet 266. Upgraded with new processor from Sonnet, upgraded RAM and a new hard disk. Both OS 9 and OS X on separated partitions.

Started to get problems after upgrading the system from 10.2.3 to 10.2.6. Tried to boot from cd, but no luck. Then tried to boot from external firewire-drive connected via pc-card. That was my mistake I guess. After the boot chime, the cursor sits up in the left corner, and then nothing happens.

Have tested with original processor, original memory and original hard disk. No luck. Have zapped the PRAM, several times. Have also let the machine be without power for several hours before testing. Is the logic board dead?
