Happy 50th birthday

I learned to program on a PDP-8/e, and I still miss it.
(Was puzzled by the green front panel; the 8/e had an orange one. Looking closely, this is a LAB-8/e: apparently, the same computer but with DAC/ADC boards for sciencing.)https://youtu.be/39ZCb65plIQ

Maybe the least obvious bit is last. It had magnetic core memory, and flipping a bit produced an EM pulse. You could write a timing loop to write memory at audio frequencies and thereby play a tune on an AM radio.

The slightly creepy thing is that it worked even with the radio turned off. The EM was powerful enough to induce enough current in the radio’s output stage to drive the speaker directly. (He does turn it on in this demo, so it can be heard clearly over the clatter of the TTY)
