Before I damage anything I will rather wait for advice!

NB: Just took another picture of how the 6-pin connector with the red end soldered to ACT pin 4 looks like in an HP-22:

Looking at the rightmost pin in the picture, it seems to be in contact with the trace that passes the pin it is soldered to. I'd have a closer look at that.

Maybe your calculator is in HP21 mode. See page 14 of the manual for reference.

I am sure Bernhard will reply with a more usefull answer soon.
