I graduated high school and then 48sx was released and I worked and saved months for it and finally saved up the $300 and bought it from a store called service merchandise.  It was under glass like in a jewelry store so I made my purchase then went to the waiting room where the product you bought came out on a belt like luggage in the airport.  I almost cried when that little box finally came down the belt for me.

oh god I remember service merchandice.. so many years ago..

It was 1992.

I sat down years ago and scanned boxes of paper, so I still have the original store receipt.  I scanned my 48sx manual and uploaded to the museum and they are on the CD set they sell.

Oh, heavens no! It must've thought I was in the UK or something. Getting results like yours now. :-+

Looking forward to using a real RPN calculator again. I wonder if the memory still has my engineering programs from university days.

You have to search for those metric size batteries over there  :-DD

Swissmicros make a full size 15c version as well as the smaller types that are credit card sized.  They also have a 42L coming out that is basically the hacked 42 with the intel decimal library. It will be the most accurate calculator on the market.   I am on the beta list to test it.

I am an RPN type up until the prime came out.  That calculator is awesome but you really need to run it in algebraic mode to get the nice print.

I own just about all the desireable HP calculators as well as the TI59 types with the card readers.  Just love sucking a card into one in the middle of a meeting.  I don't have the HP RPN with printer on one of the earlier posts, going to start looking for one again.  Bar your doors.

I pulled my HP59 out after one of the previous posts as I forgot how easy they are to program.  I love the 35 re-do as well in the same picture.  I keep a 41cx by my bed in case I wake at night and have to count sheep.  I have the 15C limited as well as an original, bummed about the limited's bugs but Swissmicros fixed them in their version.  I have a spotless 16C, a 65 and 67.  The 65 and 67 just aren't holding up though, they take a lot of love to keep the card readers running.

I've been collecting calculators for 40yrs as well as slide rules.  Have a bunch of them, and even circular ones that hang on keychains and are full function.  I'm sure Eric is reading this post.  He gave me quite a few slide rules and calculators as well.
