    Stuck in a POST card backwards. System worked before; not after (toasted a custom QFP)

    I smoked a PET ROM chip by sticking it in backwards. Luckily I already had an EPROM replacement, (I initially thought the ROMs in the system might be bad, but it turned out to be a broken trace) but I still felt pretty bad about nuking the original.

    I fried an A2000 ROM stupidly plugging it in backwards. I really know better. A2000s notoriously have that chip the opposite direction from what looks normal.

    I've plugged 65c816 into IIGS backwards before. (On that entire board, it is the only chip with the notch opposite of all other chips.)
    Surprisingly, it still works after swapping back to correct orientation.

    Parts in the 6500 family are usually quite OK to stick in backwards. Unlike other parts their power supply is all on one side instead of on diagonal corners.
    I put a TI EPROM in backwards once. It started to light up inside its window so I shut the power down quickly. It still worked fine after that. Luckily is was bonded with gold wire instead of aluminum boding. Most Intel chips would be dead in an instance.

    I've put the psu connectors on wrong. Also put a Kingston 5x86 over drive cpu in wrong and powered up the system.. Amazingly it survived but not as fast as it should have been.

    You'd think they'd keyed them to keep us idiots from getting it wrong.

    I fried the keyboard/mouse circuits on a Vectra that way.
