This short video is an addendum to my earlier video titled:
"Building an IMSAI 8080 Clone (the "IMSAI 8080 Replica" by thehighnibble.com); with Demonstration"

In THIS video, I describe this the IMSAI and its 8080 CPU handle directly accessed I/O and specifically how the IMSAI's circuits deal with the "Programmed Input" switches and "Programmed Output" LEDs, and demonstrate that with a tiny program.
