Well the hospital just called and I have to be there at 0545 hours tomorrow morning. I guess I'm first on the list which I suppose is good because the doctor will be nice and fresh....or hung over. Was told the operation would take approx 1.5 hours. My son will pick me up at 0500 hours.
Thanks for all your encouragement. I just want to get this over with and move on.
Lucky you are into Tek scopes then and wouldn't have any interest in a $100 hernia busting Curve tracer Jump on it quick someone.... eBay auction: #402956962238
Local pickup only in Carson City, Nevada.
In better times ROAD TRIP With the collection of glass inside it I would think pickup a good idea regardless. Still very cheap even in that condition.
Same seller has an Interesting lot of Test gear with some up for delivery too https://www.ebay.com/sch/Business-Industrial/12576/m.html?item=402956962238&ViewItem=&_ssn=capitolcityloans
I’d buy that aneng DMM with the BT and clock if it had a coffee pot on it too

Here is something I got from that seller in March, unfortunately they decided a cut down box with half a UPS envelope stuck in front and that loose-ish inside a bigger box was sufficient to send it overseas.
It ended up with the front panel bashed in, the plastic meter casing completely destroyed and neon indicator broken.
I can't complain too much as I did get a prompt refund. I've since spent a fair bit of time repairing the damage and replaced both halves of the meter casing with the last spares I had.

It can't make coffee but it can charge 18650 batteries

Be careful. Your probe is a capacitive load and will potentially stall the oscillator or pull the frequency off. Really need a FET probe for that stuff. Bob Pease describes a cheap DIY one in Troubleshooting Analog Circuits.
Also worth replacing the Crystal. Sometimes they wear out apparently!
Edit: also doing terribly here on the test gear collection again

Yeah, I know... but I was just looking for signs of life there. Considering capacitive loading, I've tried probing with and without a monitor on pin 15. As I know I'm able to get a consistent 30-ish seconds of oscillation with it right now, pretty sure that probing one or two output pins immediately after power cycling the thing, then moving on to the next, etc... the lack or presence of a signal is still valid data. If not, then replacing those 22puff caps should put the point to rest.
Also, I tried the 12MHz cap from the USB-ASP with similar behavior; sadly, still no 💓 output from any other pin.
I've shopped some 16MHz crystals, but all that's readily available is 20pF versions commonly used with Ardu; I might make that attempt after I track down some 22puff 0602 caps.

Oh that sucks. Anyone who packs stuff like that should be placed inside a large cardboard box with no padding and shipped somewhere via Hermes.
400 sek or quid or dollars or dollarydoos?

I don't know about crystals wearing out, but have certainly come across shattered ones in stuff at work.

400 sek or quid or dollars or dollarydoos?Euro.
Today, one Euro is 10,14 SEK, and one USD is 8,54 SEK. The pound is slightly above the Euro at 11,83 SEK.

That’s just extremely rapid wearing out .I’ve seen some of them get dicky after a few years. I’ve mostly destroyed them past forensic analysis trying to find out why exactly. I had one Racal OCXO Crystal drift so far out of tolerance it was useless.

Is it not possible to provide a 16MHz signal via your signal generator to test it with?
