In case anyone is interested, I have some spare prototyping PCBs for a Z80 CTC and combined DART board that I have been working on.
As I have to buy 10 at a time, I have some going 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 this Github (https://github.com/rabs664/Amstrad-CPC-CTC-DART) page.
