I care about having it working (I am not a 'stamp collector' :-)), and I

But actualyl, having looked at the circuit, I dont' see how an
open-circuit on the ground pin of this IC would damage any of the
imposible-to-replace components in the terminal
I could trivially desolder the IC, straighten the
pin, and solder it back
properly. But should I? What would others do?
If you care about the machine, of course! I did on an IBM MDA board.
If you don't care about using the machine, and are collecting based on
resale value, rarity, provenance, then maybe not. Although such things do
WOuld I do that???
NOT have the artificial rarity and inflated value that
a misprinted stamp
does, if the computer has a particularly unique history, then it might be
worth saving for that - "Woz mis-soldered this chip" kind of crap. Since
I am darn sure this PCB was wave-soldered, and the parts were probably
automatically fitted. So there is no chance of me being able to say
$person made this error. Not that such athing would really interest me
anyhow.
"all science is either physics or
stamp-collecting", which of those YOU
are doing, could determine whether repairs, or even modifications, are
appropriate.
As a physicist, I think I know which side I am on here :-)
