| oz2cpu:
here is a new teardown video from me, this design idea is so special and rare it is worth to mention here: https://youtu.be/nZnH6WrpSAU i think it is from 1975-1985, name of designer unknown the push-buttons for all voltages is a really special idea, I have not seen anything like this before, it dont really work in real life if you ask me :-) this one is full of loose connections and unstable behaviours, i did not repair it for now, since its low useability for my lab / collection. |
