Introduction and discontinuation dates for HP Calculators Message #1 Posted by Harald on 27 July 2012, 10:34 a.m. I have started to make a list of introduction and discontinuation dates for HP calculators in order to produce a diagramm showing these. For most calculators the dates (years are good enough for me) can be found on this very website. But for some they can't. Missing are HP 48G/GX, HP49, 49GII, 48GII, 50G, HP32SII, HP33S, HP35S and the 15CLE. I have started googleing for those, but found contradictory answers. So I thought I'd ask here. Cheers, Harald

Some missing recent dates can be found on the Hp calculator poster : Great poster from the calculator reference. You'll have to download and enlarge the image - or better buy the poster :-) I have it : great quality pictures and layout. Cheers Etienne

That is what I had in mind. Just haven't worked out how to do it yet. I have managed to do something similar using open office. But it is not as nice as I would like it. How was this diagram done? Quote: Some missing recent dates can be found on the Hp calculator poster : Great poster from the calculator reference. Thanks! That has most of the dates I was looking for. Quote: I have it : great quality pictures and layout. Might be worth getting. Sure looks nice. Cheers, Harald

Re: Introduction and discontinuation dates for HP Calculators Message #4 Posted by Mike Morrow on 27 July 2012, 1:10 p.m., in response to message #1 by Harald A lot of these dates, sometimes down to the precise day, can be found in A Guide to HP Handheld Calculators and Computers. It's by the noted subject matter expert Dr. Mier-Jedrzejowicz, and is now in its Fifth Edition, Fourth Printing (2011). If one collects or is interested in history, this is is a "must have" publication.

Here are some dates from the research done to do our HHC Calendar (see http://www.pahhc.org/2009/Calendar.htm for reference): HP48G and GX: 6/1/93 HP48G+: 3/30/98 HP49G: 5/21/99 hp49g+: 10/20/93 hp48gII: 10/28/03 hp50g: 9/19/06 HP32SII: 3/1/91 hp33s: 4/20/04 HP35s: 7/12/07 HP15C LE: 9/1/11 (from the press release) Jake

Re: Introduction and discontinuation dates for HP Calculators Message #9 Posted by Harald on 29 July 2012, 5:36 p.m., in response to message #8 by Jeroen Van Nieuwenhove Thanks! I didn't get that far yet.
