HP-65 - 1601A03058 - Full restoration

[BusyCalc]

Hello Alberto,

very nice photos! Thanks.

Why do you say you prefer a 1601A than the early ones?

Do you know any difference between years of production of the HP-65.

I (proudly) own a 1604Sxxxxx, but I wasn't aware of such differences.

In other classics it's well known the first models with metallic rim and the latest, painted. Or the marks ON - OFF of the switch engraved instead of painted.

But I thought the HP-65 was the "definitive" calculator from the beginning till the end of production. And for me, till now too, ;-)

Kind regards.

Oscar
