Sorry to bring this thread from the dead, but I need the commiseration... I am a newly minted member of the EB club.
Plugged my Bolle clone Turbo040 into the PDS slot, rather than the cache slot, heard a rhythmic buzz, unplugged and noticed my Epic Blunder... this after frying my SE/30 logic board (longer story), and finally finding a replacement for it.
I will, half-sarcastically, cry myself to sleep this week. It's a pity as well, I think my batch was Bolle's last batch of Turbo040s, since he was using his Daystar chips up.
