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!

Been looking for an HP-IB card for my HP 8590A spectrum analyzer for some time and found one in rough shape. I wonder what happened to this poor thing. Got all the parts in stock so I think I may just strip it and rebuild 🤷♂️ #hp #spectrumanalyzer #testgear #testgeartuesday

I bought an analogue panel meter recently that reads up to 60V DC full scale deflection. These are super handy for monitoring the supply rails in my #strowger #telephoneExchanges
What I love about this one is the tiny wee screw base lamps it uses for the scale illumination!
So smol!

I can't believe how long it's taken me to get hold of a printed copy of the #Marconi #Marconi2022E RF generator operator's manual.
Now to hunt down a copy of the service manual!
