@@vzaliva Great! I'd appreciate that. I have a partial copy from an online calculator collecting site. (I just sent a model M off to my son in Oregon as a Christmas present and deposited another earlier model on my other son's porch for Christmas. Gave them both copies of the manual I have, plus a manual for the Odhner ;-) ) . . . Stay safe and stay healthy!

Nice machine in very good shape. You're lucky to have one. Thanks for the video!
My dad had one of these in the olden days. Awesome machine!
I have just found one in my grandpa's house 🤩
Just got mine from Hungary today...Only took 9 months!
You have got a calculator in a VERY nice condition!
holy God that is incredible
Fuck it, I'm buying one of these. Right now. I have to order it out of Russia so it will take a while but I can wait.
Miałem taki, kupiony w komisie za 1000 zł (koloru szarego) latem 1972 roku. Straszna tandeta - stale się zacinał i belkował.

Hoi Felix,
Any chance you can scan the manual?
I would love to get my hands on one of those manuals!
I tried to find it today to scan but it looks like I've misplaced it. It if turns out I will scan and post a link here.

The zeroing device for the input couldn't be any simpler; it's just a spring loaded bar with notches for the levers to pass through.
👍👍
Great! I was thinking about scanning my copy and this saves me the work!
Did you ever end up scanning the manual? I would love to make further instructional videos for the more advanced calculations you mentioned.

@@vzaliva awesome thank you!
Is this what's known as "bare metal" computing? 😆
wow, square roots on mechanical calculator? It's insane
Google for the "TOEPLER-method" to find out how it is done.
