Thanks! It was very satisfying and not the worst thing to go wrong
for a beginner.
I was also quite surprised that such a simple component would die,
and what I find more confusing is that it died while I was using
the machine.

Picked up a few 555s and sockets and now it
works!
Congratulations!
It's odd that a 555 failed, but sometimes there's no rhyme or reason to what
fails. E.g. I was fixing some broken M7859's (KY11-LB Programmer's Console),
and on one of them a 7493 (4-bit counter) had died. That's not one of the
'problem' 74xx chips, like ISTR the 7474 being?
