MINIVAC 601 EXPERIMENTAL GENERATES A RANDOM NUMBER

My Homebrew Minivac 601 is programmed to generate a random number with 4 numbers given. Input button 2 when held down cycles the relays until let up, then pushing input button 4 shows the result.
Thanks for watching!

Why don't you replace the momentary contact push-button switches with toggle push-button switches? You won't have to hold it down.

It is thru these 'racing relays action' that the Germans of WW2 were able to create One Time Only Pads that the Allied Codebreakers could never break. It was the basis for their T32 Cipher Machine
