Steampunk Slide Rules and Other Retro Computing Devices

I never thought I would see the day when the instructional slide rule from the mid twentieth century would become a pop culture icon.  I just found this item for sale on the Internet.  Someone thought it was worth the price and actually bought it for $1195 plus shipping.


SIZE
Overall Dimensions
29" H X 15" W X 84" D
73.7cm H X 38.1cm W X 213.4cm D
DESCRIPTION
Rare, large mid-century Pickett brand slide rule that was given to teacher's as a bonus with their student slide rule orders. It would hang at the front of the room and be used for classroom demonstation. The 7-foot long classic yellow slide rule is now suspended into custom-made stainless table base. The slide rule is completely functional, iincluding movable cursor and center slide. Secondary shelf area beneath could hold glass and/or add glass to top if you choose. This is a unique mathmatical classroom artifact with sophisticated, contemporary design. Use as sofa, hallway, office or entry table.

I own three instructional slide rules: two K&E slide rules (the Deci-Lon 68 1100 and the Polyphase 4053) and the Pickett 1010 ES.  I knew there was a reason that I bought those. Where is my sawhorse?

While on the subject of retro steampunk slide rules, I did see an Otis King cylindrical slide rule that was mounted onto a cane.  This was at an antique show many years ago in upstate New York. It popped up again at the 2003 East Coast Oughtred Society Meeting.  The only reference to it that I could find with a picture was here.  I have now found another one that went up for auction on August 9, 2008, in Johnson City, TN. It sold for $750 plus the buyer's premium of 20% plus tax. So, $900 would be a fair price to say that it sold for.  I have an image of that one here below.


I have a birch limb that I've always wanted to convert to an Otis King cane, but I can't quite bring myself to destroy a perfectly good Otis King slide rule to make one. I have tried to find a non-functional  one to buy for that purpose.

I also have seen a Norden bombsight that was converted to a coffee table.  The metal shield was removed on the top and replaced with glass. Cool! I wish I had a picture to show you.

If anyone has seen any other retro type computing device that has been converted to a useful modern item (or even not so useful item) I would like to know.  Please leave a comment or contact me and send an image. I'm sure that some of the other readers of this blog would like to see it.

I found another one -- A clock with a slide rule pendulum

Otis King's Cylindrical Slide Rule


This is a stock photo of an OK. I will insert a photo of mine later

I just opened the latest issue of the Journal of the Oughtred Society.  This issue has a picture of an Otis King (OK) slide rule on the cover. I have to unpack mine and take some pictures. I think the most interesting Otis King that I have is the Model N.  It is an early production serial #8365 with the holder 422 scale and the cylinder 424 scale. It is an all chrome plated model with white numbers on a black background scales. It came in a coffin case with the Holburn Viaduct address inside the lid. Mine is in very good condition. According to the JOS article this month it looks like there are three other Model Ns that have been recorded in the literature. However, according to the Dick Lyons table of OKs (Click here).  I found 11 type Ns listed with two of those being white numbers on a black background.

I remember when I bought this OK in Denver at a store on "Antique Row" on South Broadway about 15 years ago. I think the store was called the "Packrat".  I was in Denver doing some forensic work for a client located downtown and had some time to kill between meetings.  I had heard there was one antique store on South Broadway that specialized in scientific instruments.  The store was crammed full of gadgets. There were many pieces of surveying equipment or other pieces related to the mining industry. I can highly recommend it if the store is under the same management.  Prices were a bit steep there. It has been a long time and Ebay wasn't really around then.   I knew this particular OK was different than most of the other OKs that I had seen up to that point. Much has been published about OKs in the literature since then. My suspicion was well founded.  There is something about an OK in the way it feels and moves as you operate it that is very satisfying compared to many other slide rules.
