SCELBI Keyboard Interface All Hooked Up and Running

For now, I’m using one of my PS/2 adapters (on top of the enclosure) to connect to a PS/2 keyboard. I was going to cobble together a cable for my reproduction Datanetics keyboard, but it requires -12 volts, which would have to be generated separately just for this keyboard.

Now I can focus on the Oscilloscope Interface.
