Guys – Did you say Party phones that went along with the patch panel? And scary glow of the lines when a lightning storm went through?

I can (barely) remember when rotary phones would have been called "high-tech", except that the term had not been invented yet. Would you folks know what to do if you put a phone to your ear and heard someone saying "Number, please"? (Wouldn't that be a cute feature when opening a 'phone app?)
And there are still plenty of telescope mirrors that predate Roland's triplets, and even predate Roland, that are still doing yeoman duty today.
