Last episode, the PDP-11/23 11/03 Hybrid we were building absolutely crushed me. Well, to be fair, we never even got as far as testing the CPU, we got crushed by the power supply. I threw everything I had at it, and emerged the very opposite of victorious. I retreated to my corner, and armed myself with more knowledge, and now, stepping back into the ring for round 2, I absolutely will emerge victorious! How though? Well, you’ll just have to watch to find out (it was negative voltage).
