Wow. Old BIG commodore desktop programmable on ebay


How old is this thing? The guy is touting it as the first programmable desk calculator...but I don't think that's correct. :-)


Anybody have suggestions as to what may be the most economical device available with a Nixie tube display?

One of my minor goals is to have a working Nixie device some day . . .


There was a pawn shop that put up a collection of 3 old calculators on Ebay a few weeks ago. One of them was a Sharp Compet nixie device. Starting bid was $20. No takers.


I once had a Monroe desktop calculator with nixie tubes. I traded it with Bruce Lamm for a copy of his book on calculator.


Does your "device" have to be a calculator?

HP (and others) made all kinds of test equipment with nixie tube displays back in the 60's. I suspect these can be had for just about free if you can find them. Look for a frequency counter or a DVM.


All very good suggestions. In particular, the non-calculator idea appears to be a fruitful avenue of inquiry -- an eBay search for "nixie" (in titles and descriptions) yielded several apparently usable multimeters, for example.

Thanks again!


does my old freiden count? :)


I've picked up some nixie tube calculators for $2-20 at the office liquidators around town. They're usually marked $20 but it's usually not hard to talk them down. I mean, come on! It's a really old calculator! I could buy a new one for $5! :-)



Your post reminded me of an old calc of mine that was somewhere in one of the closets that hadn't been seen in years. Found it! It was a Heathkit put together around 1972 (model IC-2008-A). I thought it used nixie tubes but these don't seem to look like them. Any ideas?



You can buy a manual from here:


Here is a nice site for nixie lovers:




Paul: a Google search for 'nixie tube' will offer many good places to look at. I specially liked,, and

Yes, I have been bitten by the nixie bug, and plan to design and build "something" nixie-based...


It's actually a Casio, see this very informative page on it:
Hmm... a $1200 buy it now price... Someone is optimistic!

I'm also a big fan of Nixie - finally got my hands on my first Nixie calc (a beautiful 16 digit Sharp) a few weeks ago.

Granted, the calculator I desire most has a CRT :-)


It's already at $900.
