Just received this pre-assembled PCB from PCBWay. Super high quality with very small SMT components. If you need mass assembled PCBs then use PCBWay.
To see how the board is used with a Z80 Computer then check out this video

@NoelsRetroLab I use MacOS and RVM. I found it excellent for coding Z80 on the Amstrad. Command line is powerful. I've done a 'how to' video on using it. Ready? Z80
