Z80 Arduino Shield With Arduino Mega Bus Analyser

This is a look at my Z80 Arduino shield. It uses an Arduino Mega as a flash chip programmer and bus analyser. The Mega can also drive the system clock while monitoring the bus signals, giving full tracing of all bus operations. The PCB can accept Uno footprint shields for I/O and can run as a single board computer when the Mega is removed. More details on my blog: Code and PCB files on Github: The PCB is on Dirty PCBs:
