Hi Geoff re-reading your words I understand (and of course only this should have a sense) that you mean the paper black cover (the bottom of the battery compartment) should be removed and not the keyboard. I'll do it asap, while fixing the bender wires bad solder problem.

I would like to avoid to open and close too much the calculator: broken posts are waiting for me every time like a doom Smile
The first thing I did today was therefore to reassemble it and assuring that there were not bad contacts, this time, of course not related to the half board but in the upper area.
