For all you CPC Freaks out there who are running out of space revaldinho on the CPC Wiki site has designed a 3 Slot Backplane for CPC464/664/6128 computers. It gives you 3 Mother X4 compatible slots and each slot can be powered by an external supply or the CPC using Jumpers. Comes in handy when like me you plan to have a M4 Wi-Fi card, 512K RAM Expansion and a Multiface 2 running at the same time. The Gerbers,Eagle .brd files and BOM are all available on his Github Here
I have built 5 myself and they work great so would recommend them. I have one left that is spare and available if anyone is interested PM me, comes with a Edge Connector ribbon cable ( not Centronics ) but will need three Jumpers ( I have run out ).
The spare one has sold now so I have none left but can help anyone to get some made up if they want one.
