HP-67 - 1909S02534 - Card reader advice requested

[albertofenini]

You wouldn't believe how we fixed it (at least the reading)...
We tried another Standard Pac, simply because working on another HP67 we had some trouble in reading the cards that we usually use for our tests ...
Now it reads
However, the last column of keys is not working, nor it goes into programming mode ...
We had noticed that the keyboard PCB had some traces kind of cut, but at the time we didn't pay too much attention to this,
we will reopen it and try to fix this ...
Thanks to everyone !
