Hi guys, thanks for responding

This is why i came here - this is all very new to me and guidance is much appreciated.

@Raft - I have viewed the schematic and i can see that I was looking at the top tracings and not what is on the underside.  I have highlighted where i believe is where the bank 1 channel starts and ends - does this look right?  I guess i can check the solder connections on the the underside to see if it looks okay, but failing that I'm out of ideas.  I have also attached that photo above with what i thought was a broken trace and highlighted what i was talking about originally.

@McArti0 - well, I was told that if the keyboard wasnt working, that it would go through the AY and IO chip.  As I said, this is all new to me.


Any ideas what I can do / try next please?

That trace isn't broken. The copper has just slightly oxidised under the stoplack layer. The AY chip has most likely failed on that particular io pin.

Bryce.

here we go :

Utiliser La Rom Addon - iMPdos

Have a good fun!

Be careful: it's not compatible with the latest UniDOS (unfortunately! I would love to be able to run SYSco on the latest version of UniDOS).

Try pin14 AY to ground and next Pin13 to ground.

If AY Pin13 give You "97532" then Try cross pin13-AY to 74LS145 Pin 1,2,3,4,5,6,7   and 9,10,11

Try by multimeter continous Pin13 AY and all pins keyboard connector.

I've gathered these examples and put them into CPCBasicApps, so they're easy to run and explore:

Hi Marko, thanks a lot, these are very cool and inspiring examples!

Do you think the photo shows pin1 AY?
