Some carnage it was indeed! Ended up replacing all ICs except the main TMS9914. A wonder it survived. The other chips were mostly a dead short to ground. No surprise the supply rail was a little scorched. I really wonder what happened here and what became of the poor instrument is was originally installed in…
Now at least it got a new life and my 8590A spectrum analyzer is happily communicating with the outside world!
