In case anyone is interested, I have some spare prototyping PCBs for a Z80 DART that I have been working on.
As I have to buy 10 at a time, I have some spare, but sorry UK postage only.
These PCBs are part of a family of boards I have been creating and they are nothing more than a bit of fun to learn about the Z80 family of peripherals.
You can find more information at GitHub Page (https://github.com/rabs664/Amstrad-CPC-Z80-DART).

below is a completed board.

And this is the board under test connected to an FTDI Serial Adapter. Note the CTC and PIO boards behind the DART board.

Next possible step: Cloning and enhancing the Amstrad Serial Interface?

Hi, not sure what to do next. Could change to an 8253 timer and match the addressing scheme of the Amstrad Serial interface.
I have built an 8255 PIO, CTC and DART board, could combine them all on one board as a general IO board.
But I have some DMA ICs to play with next.
However, I have no idea yet how they are going to interact with the CPC. May need help when I get to it.
Keep us updated! :) :) :)
