I used to have 3 calculators I used in my DarkLab... one was solar powered but it lost data unless I was quite close to a safelight...

My old programable calculator did not read properly unless you squezed it in just the right spot. Missing decimals were always fun...
but i just couldn't throw it away.

I guess I do need a good new one!

The last couple were bought from 1$ stores; and they don't come with a whole lot of skills!
