Here is the log from the ESP32 for Boot, 8080 Power on, and 8080 Power off in case there is something useful there. |

Issue #2 is resolved after I initialized and ran CP/M. I am assuming there was some issue with the random bytes before being initialized. Item #1 is still there, is a 2-3 second delay after turning on the soft power button normal? |

Assuming the delay is due to the simulation startup. |

I am building the 8080 and at the point of powering up the 8080 as shown in the video #19 and have two issues:
When I power up the 8080, there is a delay of 2-3 seconds before the LED light. This may not be a problem as most of that time is the ESP sending out text to the PC terminal emulator.
When I put the 8080 in Run it freezes. I can't put it back in Halt, and if I press the "Off" switch, nothing happens. I have to reset the ESP to unlock it.
In the boot sequence, there is one red error message "E (1046) nvs: Error (ESP_ERR_NVS_NOT_FOUND) opening NVS handle!" I have tripled checked the ICs and solder joints and everything seems OK.
