Simple PCB with labels and header pins for the Amstrad CPC Expansion Bus, compatible with an MX4 connector.
As part of any build or debugging you often have to probe certain signals either with the multimeter or oscilloscope. Having to remember the pin position of signals can become a bit of an annoyance. So I created a simple PCB with labels and pins to make life a bit easier.
The pins have all been traced and checked back to the pins on the Amstrad CPC PCB.
As I had to buy 10 PCBs, I have a few spare if anyone is interested. Sorry UK postage only.

great.
would you also share the Gerber files? I might order some PCBs soon anyway and this is a great idea.
Sure, there is a GITHUB repository with them in.
Amstrad CPC expansion breakout PCB (https://github.com/rabs664/amstrad-cpc-expansion-breakout).
If you can't find them there let me know.
Soon they should be available on the Seeed Studio Gallery but they are still confirming by post.
I have traced and checked the header pins back to the PCB on my 6128 but I have mainly been using it with a small mini rack based Z80 that I am building, where I use
@revaldinho backplanes, so I think it is ok.

@Rabs Thanks for the Project.
I also have ordered 10 Boards (Coming Soon)
I will make them available for " AUSTRALIA Only " at $8.00 posted
Thanks for all your work
Keep Safe

@Rabs Thanks.
Time for some testing!
Hi
@Richard_Lloyd are they assembled,for you just have bare boards?
Using the breakout because I forgot to add IORQ and WR to the PIO board.

The post is about the front board (@Rabs breakout board). I got the bare PCB from him and soldered the connector and header pins myself. He has more PCBs if that's what you're after.
The two expansions behind are
@revaldinho's EightROM and CPCLink. I ordered the boards and components and built them myself. I have spare boards for those if they are what you're interested in.
@Richard_Lloyd it was the breakout board I was interested in, thanks.
@Rabs do you still have any?
I am interested in one of these.

Hi, probably easier to buy direct from seeed studio rather than me send you one from the UK. But I think
@Audronic may have some.

Hi Zhulien
I have some Naked boards available for $10.00 posted
PM Me if you want one.
I will need postal details

@Rabs Thanks for the Project (Breakout board)
It certainly makes for Quick Diagnostic of the Various lines used
also it means I don't have to open the computer to do a quick check
Included is a quick Table that you can print out for use during tests
Well done
Keep Safe
