I still have an ASR-33 TTY (though it would need a major rebuild after all the lubrication turned to an amalgam of dust and tar). Before tha I had my own keypunch machine (and I still have a lot of blank ready-to-use IBM punch cards). And I did keep the APL ROM out of a dual-head Centronics printer before scrapping it. Likewise, I kept a type ball from one of my "networked" Selectric printers. Though I never parted out my daisywheel printer -- it cost TOO DAMN MUCH to scrap. And CP/M wordstar had built-in drivers for it (but it required THREE S-100 Bus printer cards to drive it, as I recall). My list of technical antiquities (many younger than me) goes on and on -- a lot of my gear is bakelite from the "pre-plastic" era, if you can imagine that... I even have a bakelite ViewMaster 3D viewer. And I have NIXIE TUBE calculators and NIXIE TUBE multimeters (19-inch rack mount, of course)... And I used to actually USE this stuff. Kids these days just have no idea how easy life is for them, eh?
EDIT: Hmm... Now I have this strange desire to hook up my daisy wheel printer to a modern-ish dev kit (STM32 perhaps) and make it print. That thing only has about a dozen hours of use on it. Back in the day, people even printed "graphics" by fractional movements of the paper and print mechanisms, while trying desperately to wear out the '.' (period) on the type wheel. --- But that desire will pass...
