Feelin loneli again??? :lol:

huh? simi lonely?

Chim leh.. got instruction manual on how to use or not? :lol:

I don't know, I haven't got it yet. It's my dad's lah :lol: He whatsapp'd me the photo, said he'll pass me. :mrgreen:



When he first started out as an engineer back then, he used this. Apparently the other side is a slide-rule. He brought my son out to watch movie today, wonder why he didn't pass to my son. :?

I think it's quite hard to find a working mechanical calculator.

Think I still have a 15cm slide rule somewhere, but must say I have never knew how mechanical calculator were in the yesteryears.



It's quite interesting, found the instruction here: http://www.sliderules.info/a-to-z/addiator.htm" false;
