Issue with a MX4 board?

[angelcaio]

Thank you very much for your answers.
I am waiting for the arrival of the 5V 4A adapter. Finally I ordered this one with 5.5 mm x 2.1 mm connector.

If I understood correctly, i need a Mother X4 whitout diodes and supply the power for the ensemble  (CPC + Mother X4) with the 5 V input of the CPC, and NEVER plug the Mother X4 into power.

If I do this this will work the cards that I have connected in the adapters to edge50: lightpen and ddi-1 clone.

Is it like that?

This is how I use it (when I use it). Interestingly, @Audronic does it the other way around if I understood him correctly - he feeds the power for the whole CPC and the expansion boards into the MX4 socket. According to @TotO , this is "a dangerous method" (not quite sure why either).

Ok, thanks LambdaMikel

True.

He should cut with care the two diodes if the goal is to no more use the MotherX4 without PSU to see the result.
Or, I can sent him one without diode to do the tests... (and if OK, to return me the other)

Hi TotO, I would be grateful if you would send me a MotherX4 without diodes to test this
If so, I send you a PM with my address
Thanks in advance.

Sorry, I was not notified about the answers...

TotO: This hack is dangerous. You can damage your CPC or the connected expansions if later you forgot and a PSU is plugged on the
MotherX4.

No, it is not. If you remove or cut the external PSU diole, it is no more possible to power the MotherX4 externaly.

I will do.

SOLVED!!!
Thank you very much TotO for the replacement of the MX4. My CPC woks again ok.
I have connected the lightpen with the Duke's MX4 to edge adapter and the DDI at the end of everything. I powered everything, including the AMX Mouse, with the monitor and all work fine.
