Just a quick question, has anyone else had something this extreeme happen to them when setting up a computer?
Not first-hand, but we once received a DEC PC server, a big honking thing on wheels, roughly the size of two mid-towers side by side. Booted up and ran Windows NT without complaining. However, upon inspection of the innards, we found a 2*2 cm area on the motherboard which was burnt out. As you touched it, burnt PCB crust fell off. Nevertheless, it worked without complaining. DEC quality.
On the Amiga side of things, I've had a SCSI ribbon cable catch fire. Just the cable, just one of its 50 leads, but burning with a large flame. Luckily, the controller survived, but the drive was discarded.
