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.

Cut my teeth on a TS1000 (ZX81) and ZX Spectrum 48k back in the 80's. There was a Z80A cpu in the Spectrum. Amazing how the old systems just go on and on.

Yes, you can still buy Z80s, believe i tor not.

[@youreale]

well done! nice project indeed.

[@alnoorratansi9364]

Great project, can you show example how to run code

[@menadue]

I'll see about doing a video about that.

Nice !!

EEPROMs don't need UV..... skips a whole step....

[@menadue]

Yes, I have given up on EPROMs, which is why the Arduino is used as a flash programmer and emulator here. No UV erasing needed.
