    USB to 9 pin rs232 serial (active), 9 pin to 25 pin serial, 25 to 9 pin serial, 9 pin serial to ps2, ps2 to AT, AT to ps2, ps2 to USB.

    And 99% sure there’s no USB functionality there as that last adapter is for a mouse only.

      There will always be a special place in my heart for serial, where I can just jam in a paperclip and “guess around” with a voltimeter till I figure it out.

      That’s a lot of adapters to get from USB to USB. There’s probably a metaphor in there somewhere.

      What’s the adapter between the 9 to 25 pin and 25 to 9 pin serial adapters? Looks more substantial than a typical gender changer, maybe one of those dip switch adapters upside down?

        i would have guessed a null modem adaptor, cuz - why the hell not! but… assuming the USB to serial is a typical DTE (M) then the 9pin to 25pin would likely be (F) to (M), but the potato markings on the mystery adaptor seem to suggest M/M… so… 🤷‍♂️

        your breakout box suggestion is a reasonable one.

        Bureaucrats. A million complications to do the same thing but slower.

      That USB to serial might have some diodes in it, preventing a magic smoke release. But after all the decades, the funny thing is the ground pins still go to ground.
