    Just found this channel, and I like it. My daily calculator for all is an HP 32SII. I have programmed it with a small budget program that tells me how much money left for rest of month.

    Interesting device...people of that era were smarter than we are in many ways.
    Very informative video thanks for posting.

    Hey thanks for opening yours up. I've never been brave enough to open mine but have been curious to see the inner workings. But unfortunately because of focus issues and your man hands (lol) I wasn't always able to see the things I wanted too. So giving me incentive I threw caution to the wind and cracked mine open but was surprised to find the lid with the tabs, thinking it aluminum, to be of steel. I don't know how you managed to put yours back together but I just wedged the alum. base back enough, on the side with just 3 tabs, to slip it out. I obtained mine from my father (he was 85 and was 35 years ago when the transfer happened) having probably bought his while working in the general area at the time. The felt bottom covering was a tiny bit lose which allowed me to see that there was an inked date stamp of Oct. 28, 1949 along with a metal stamped "Pat. Apl'd For" so my guess no patent was obtained and so probably the "adder" was based on pieces of currently known tech. Thanks for sharing what you found and hope you got it back together.

    Thanks Joe. I haven't seen one like this before only the smaller squarer more "pocket" sized versions. Fascinating to see inside and now simple yet ingenious it's design is. Yes, as you say when you pull the clearing rack it reminds me of the sound of pulling back the slide of a BB gun I once owned. It's come up beautifully shiny. Very interesting piece of kit.

      I used to have one of those pocket-sized version as a kid - grandpa probably bought them for us - but alas they didn't survive childhood.

    wow, thank You for sharing this heirloom of Your family with us. Never seen one of these before in my life. I really do like the simplicity and elegancy in its functional design. Wish I could call one my own. As You've shown the interior of this little " magic box " it immediately reminded me of some old 74... TTL logic chips , registers that add up to 9 and than create an overflow to trigger the next chip, and so on. This is the exact same device, only build from aluminum. The reset pin being a ratchet here. Very cool device, I really envy You possesing one. Think I have to go fishing in th e bay for one !

      It's a good analogy you make between the mechanical logic and electronic.

      Joe Van Cleave. Whoo-hoooo, I found one for a reasonable price in the bay.... eagerly waiting for it ! It' s coming here all the way from Amery, Wisconsin . Guess I was lucky, finding one for small money. BTW, it's an older version, missing the " ratchet " and the small numbers for substraction. Resetting the device has to be done wheel by wheel .

      Nice find! Let us know how it works...or post a video.

    I picked one of these up (with a different, green paint job) quite a while ago, and mine still had a stylus with it. Didn't come with the manual, though, so I had to learn about the method of complements on my own. I got some non-monetary use out of it by tracking hit points and magic spell slots in Dungeons & Dragons. Good bit of fun.

    I was really excited to see this video. I own one of these. I don't remember where I picked it up, but I have an interest in slide rules, so it was picked up around them. Mine came with a metal stylus. I own an old Barrett adding machine, so the simplicity of this thing surprised me.

    I recently acquired one of these. I haven't made the time to clean it up yet.

    • @Joe_VanCleave
      @Joe_VanCleave  Před 5 lety

      These are fun to use. Did yours come with the metal stylus?

    • @dianemaher3538

      @@Joe_VanCleave I don't recall seeing one. I picked up several adding machines from this estate. Some were pocket sized; one of them is even a pencil box. I do recall one of them had a red stylus of some sort with it.
