calculators without OFF
Accidentally I ran into the opening post of one old thread:
Quote:"Hewlett-Packard HP-15C calculator. I bought this new in July, 1985 ... The only real problem that I know of is that I can't turn it off unless I pull a battery. I don't see any 'off' function on the keyboard and I don't know if this has an auto-off feature after so many seconds of non-use."
("Ok... Own up! Who amongst you put this 15c description on eBay?")

The text and especially the subject gave me a good laugh. But then I realized I do have a calculator without any OFF function - CATIGA CS-110:

the manufacturer's page

There's no way to switch it off. It does it itself after something like 5-7 minutes of inactivity. Or just pull the batteries :-) Do you know other calculator without OFF?
