ZX80 revision 2 PCB.

This is a blank ZX80 revision 2 PCB which I have reversed engineer from the original Sinclair design, keeping the same component layout, curved tracks and silkscreen.

Let me know if you want a copy of the BOM.

I have built this and it works perfectly. See the last photo for an example of the display output.

Note: The photo of the fully assembled PCB is for reference only and what it will look like when populated.

You will only be receiving a blank PCB and will need to source and solder in all components yourself.

Please contact me if you have any queries and I will be only too happy to answer them.
