Read the LP manual at page 13. If you use an HP-21 board you have to connect pin 1-5 of the "external signals connector" with pin 5-9 of the ACT. Alternatively if you didn't change the LP as you received it, which is for non HP-21 board, just press the "." button before inserting the battery. This is meant for avoiding soldering to rearrange the keyboard wires.

The upgrade can be made from the top of the board, but I don't recommend to solder directly.

No luck with your tips. I get the reset but no exepted action by pressing the keys. Is there a way to check the connections between the ACT Pins and the LP Board? Or is it worth to unsolder the LP and see what is wrong? It looks like the rows are swapped from left to right and vice versa. but i have no digits. CHS is on CLX.
