I recently acquired my first scope, a TDS320. I know this isn't regarded as a great scope, but I got it cheap and in working condition, and my only real use case for it is occasionally diagnosing vintage 8 and 16 bit computers that run at a few MHz, so I can't complain. :-)
Anyway, the scope came with a couple of aftermarket 1x/10x switchable probes that of course do not have the little sense pin on the BNC, because they're switchable. I have read the entire TDS320 manual, searched the forums here, searched Google... for the life of me I can't find a way to manually set the scope to 10X attenuation. I do see an option if using an external trigger where I can set the external trigger to 1X or 10X, but not the main channels.
I did see a thread on the forum here about making your own 3D printed adapters to engage the sense ring on the scope with a resistor. Are there some scopes where there just is no way to manually set this? The little 3D printed adapter rings are a great idea, but alas, I do not have access to a 3D printer. :-(
I could go buy some 10X probes with the pins of course, but that's a lot of money for what is essentially a toy to me that cost < $100 to begin with. Plus the probes I have seem to work just fine, so don't fix it if it ain't broke, right? :-)
