HP41 card reader repair

[Karel]

Thank you Andi.

The 41cx got port block from 41c for the time being. I am waiting for new ribbon from calculator store to repair the block for 41cx. It had bad battery leak. I cleaned the board thoug.
The 41c tallkey fullnut was in bad shape as well but no leakage as far as I can tell. I used its port block in 41cx while working on the 41c keyboard and display board.
The display was badly soldered on and there were snots of solder everywhere. It must have shortened some traces - the display was faulty. Few segments missing.
