Z80 now running on the prototype board

 

Above you can see the PicoScope showing the clock up top on channel A and A0-A15 address lines on the digital channels at the bottom.

Here you can see the PicoScope connected to the prototype board.  Clock is run by a crystal connected to an inverter you can see as the smaller chip on the right side of the board.  The larger chip is the Z80 itself. The colorful ribbon is the connections from the address bus to the PicoScope's digital inputs.

And this is how I've verified that the CPU is running and attempting to call out to memory for a program to run. Next I need to hook up an EEPROM and some RAM.
