Here's the 33E being stripped and cleaned with the 33C back together and running on the right. The glass is full of keys and other bits and pieces soaking. The keys came up very well on the 33C, but the 33E's keys are UV-affected from a lifetime of hard work! They'll be fine though when I'm done.
You have done a good job there Chris. They look like new. They have gone to a good home. As I said I spent far to much time using them (and others) before decent computers were developed.
You are quite correct that it was the positive feedback from the keys that saved a lot of time as you just knew each keystroke was good.
The RPN always appealed to me as well as it was far more logical than the foolish answer (=) key.
They both look as good as I first saw them all those years ago.
They're both in great nick and will be shown from now on without batteries for fear of contamination or leakage.
Yes, RPN notation is brilliant. Far more logical (to my mind anyway) than algebraic. Always was since 1979/80 when I had my first RPN calculator - the HP32E.

Chris,
nice job How come the display in the 33E is red in the refurbished post, but seems green a couple of posts back from that when you've just received them from Bert?
post #82, - the right hand side picture, but the left hand calc on that picture. It says "11424" in big green numbers. Definitely looks green on my screen
it's confession time. After a closer look, I don't think that's the display at all. It looks to be some sort of writing above the display area. Sorry for the confusion.
if your that much into calculators and you can work magical wonders then you can have my old workhorse. this is a unique package as you can see, I have had the motherboard changed once to the upgraded model after the c. i bought a new set of batteries for it a few years ago, went to use it one night and it didnt work, opened the back and then i cried - one battery failed bigtime......... I loved my 41C. you can have new PC's but it doesnt take away the feel and accomplishment of the 41. my current calculator is a 32S2 - functional but not what i really like.
i used to have the magnetic strip reader but i loaned that to a old work mate many years ago - it got burnt in a garage fire he had at home - is home office was at the rear of the garage. it was worth a small fortune and had all of my programmes with it on strips.
Firstly, a big thanks to H0ughy for his old HP-41CV. I completely tore it apart to detoxify all the internal contacts after the battery conniption, and now it's working - for most of the time. On occasion it will flicker and reset itself, but it's becoming more reliable the more I work on it. It's not one you'd probably want to rely on any more, but it works fine as a museum piece!
Secondly, my Elektronika MK-61 arrived from Russia today. It's a beast. It's a programmable RPN calculator that the Russians have obviously modelled off something like an HP-33. The buttons are lousy, and the construction is, well, cold-war Russian - but it's a VERY cool item! It works very well and I like the green fluoro display. Note-worthy is the inclusion of the total circuit diagram, in case you need to fix it yourself. Love it!
I was just at our local recycling center and found two manuals one is for Casio fx-8500G and the other is for a POWER GRAPHIC fx-7400G do you want them for free
Will do!
What a top bunch of blokes you are.
