Hi Diego,
I tried to contact you from your Clonix site about the replacement flex PCBs you are describing there. Are there still some you would sell? I would be glad if you could contact me about this via forum email.
Does anyone else know a source for flex PCBs to repair the HP 41? Can they be (easily!) DIYed? Is there another way to replace a corroded flexible PCB in order to have a working module compartment?
Thanks to all!
A.
