This wasn't wire wrapped that was back in the TI 99/4a days.

Obvioius was that a motherboard has no wire wraps. But with kynar
wire experience and that posted ampere number, then you can appreciate
how much current would be required to also harm PC traces inside that
motherboard. IOW why a motherboard trace feeding a memory slot could
short so much current and not be damaged.

Brand name computer power supplies meet ATX standards as did power
supplies 30 and 40 years ago. Foldback current limiting would be
necessary for a long list of reasons including proper operation of the
overvoltage protection circuits, the 'shorting all outputs together'
test with no damage, and basic fire safety. An HP supply will most
certainly contain foldback current limiting which explains why a
shorted memory card did not cause motherboard PC trace damage.

Had that short been via a data or address trace, well, damage would
have been probable. Current for Kynar wire puts into perspective why
a shorted power supply did not cause motherboard damage.
