Awesome, Gerson, awesome, and yes, I like it very much !

Thanks! I’m glad you have liked it.

On your brand new HP-15C CE you might want to try Ramanujan’s original approximation which fills up the display with the very same digits in Moravia’s advertising:

63 ENTER 5 √x 15 * 17 + * g LSTx 10 - / 25 /

Divasson posted above that The Calculator Store has already sold ~900 from the 1,000 units shipped from Moravia, and that was days ago) so I'm considering buying another one from them before they're gone for good, just in case.

Mine arrived some 6 days ago, looks great and works like a charm, and I haven't had this much calc-related fun since ages !

I have ordered mine from the same place you have, but I don’t expect to get it any time soon as Customs bureaucracy is somewhat complicated here. Anyway, by what I’ve been reading in this thread, it is worth the wait.
Don’t hesitate to get yourself another one if you have a chance. When the HP-15C was released I purchased three units from Samdon’s Cable, for their initial low price (under US$ 100.00 each, I think), before prices were raised. I have only one left, one went to my younger brother and one was sold to a friend with no profit. Yes, I still remember when I got my original 234B unit forty years ago, I still remember how it smelled like when brand new. But I don’t think I will read the whole manual again this time :-)

Best regards,

Gerson.
