Mea Culpa, Mea Culpa...
Just fired off the address - your email was stuck in my Junk Mail box, and I don't check that as often as my regular mail.
I appreciate your generousity concerning the calculator. Tell you what - I've got a minature library's worth of books and manuals gathering dust. If there's one you're looking for, let me know; if I have it, I can mail it to you, free of charge.
As for the LCD, that should be easily fixable - Radioshack may not be a thing anymore, but its cyber counterparts live on.
Gratias tibi ago!
