Smallest scientific calculator available?

K&E Log Log Duplex Decitrig.

At 317x41mm it's not even in the running, sorry Don.

But battery life is a plus. You can also get a self-oiler for them.

I think some of the better calculators have a self-Euler ; )

The FX-82 solar doesn't have a battery life problem.

I've done away with just calculators since I got my first PDA years ago. They all have excellent scientific calculators available for free download, and, of course, they can do many, many other things, too.

My present system is a Palm Zire 31 with the SC-103PU scientific calculator and the VisualCalc and MemoCalc programmable calculators. It really does fit into any of my shirt pockets, unlike some of the fancier ones I had before.

And, yes, I still have my K&E slide rule from the early 60's. My dad gave it to me when I went away to college -- he got a huge discount because the shipyard he worked at bought them by the cratefull for their engineers.

I have one of those - not working. I also have a Sinclair Scientific AND a Sinclair Programmable.

I still have my Otis King 66" cylindrical!

Yeah, I've got a PDA too, and yes it can do many many other things. But I want just a calculator, not something that does a zillion other things to chew the battery life in a week. And call me old fashioned, but I like a calculator with real buttons you can press.

Dave :)

Okay, you're old fashioned. :)

I still have my HP15C. Works for me though if there was something smaller with its capabilities I'd go for it.

I paid (I think) $20 for my CFX-400 back in the 80's. The part of the case that supported the band broke off after about 10 years, so it was no good as a watch, but it was still functional. I sold it for something like $300 many years back to some guy in the US, even before the days of crazy eBay prices. He had a good case and wanted the working electronics.

Even not working, yours might be worth something...

Dave :)

Someone just paid >US$100 for just a CFX-400 case:

Dave :)

I picked up few 'made in china' tiny sci-calcs like that for $4.00 at Big Lot.

They carry all kinds of close-out stuff there. Do you have one in your area?

Another good close-out store in the norteast US is 'Ocean State Job Lot' they have them too.

My Picket N600-ES Log Log Speed Rule served me well thru college. It's only 153x30 mm, 34 g without the carry case. Works well in moderate light.

I used to have a CFX-200. I just saw a working one on Ebay for USD1000. :-(

I wonder if the user manual will fetch anything?

Was wondering that myself, I still have the CFX-400 manual somewhere...

Dave :)

My "area" is about the size of North America and located somewhat below the equator! We have a few similar stores though, will keep an eye out from now on.

There are scientific calculator programs available for some PDA's, and the smallest of these are possibly in the sort of scale to be considered. Some small models are available with 'limited' scientific abilities. Canon, do a model in a cheque book case, which saves on wasted space. The smallest solution that is probably likely to be really convenient though, is that there are scientific calculator programs that can run on many mobile phones now. Some of the 'flip' designs here, are tiny. 'Calculator Mobile', runs on the SmartPhone units, and I'm sure others are available.

Best Wishes

Any surplus Sinclairs out there?

Steve.
