Superdecade Games: Reverse Polish Notation Calculator

I don't remember exactly which calculator I first had but it was very much like this and my "big" Christmas present in mid 1970s this is the HP-35 Calculator from 1972. Look at the cost! It is still my favourite calculator of all time. Great keyboard, and used Reverse Polish notation logic for entry, which seemed so logical.

HP 48GX by Hewlett Packard. I picked this up at a local flea market for 25$. It goes on eBay for upwards of 100 bucks! I love the HP's reverse polish notation. If you haven't given an HP a try, do! Next up, HP 50 GX.
