HP-28S Battery Cover


I just received my battery cover made by Adam Jones, it is a perfect fit and works great. Thanks Adam! I will be able to get a few more years out of this calculator. This weekend I am thinking about going to a local hardware store to get some dark spray paint which I think cosmeticaly will make it look better.


Are these available general purchase yet?

Just drop me an email. I have a couple made right now. I have more to do, but need to rebuild my bending tool. I broke it!

I was thinking of getting these things treated with Black Oxide. Stainless would accept that well. Let me know if you think that's worth extra to you.
