    Try it!

    :lol:

    Removing a pin from underneath a CPU would undoubtedly destroy it. Most of those pins are bus pins and if you damage one of them then any address you send/receive is lacking a...

    I cut the damaged pins off. The CPU loses a few commands of the instruction set but as long as 99% of it is still there it works decently well and the kernel panics don't bother me that much.

    Yeah, I agree. Though it depends where the boo-boo happens. And what the resulting damage is. If your short circuit burns a part of the PCB, or knocks out half the chips on a board, it's not okay.

    Fine. Then just the historical value.



    Perhaps maybe guardian of vintage ALTAIRs? :D Just kidding, I'd prefer not to get a third one but will accept it if the alternative is trash or...

    The value, both financial and historical, rises exponentially every year the longer you own it. When MITS was sold to Pertec the 8800 wasn't worth more than what it sold for back in the day. But now,...

    They could have listed at a higher price, like $49.99 or even $99.99 and made even more :)
