If you want to download the fantastic Thomas Okken Free42 program please go to this web site In my opinion Free42 is even better than the real HP-42S. This because I suppose most owners don't have the printer (and it is not so useful) and also haven't had a HP-41 prior to HP-42S. Two things I really don't want to see here are PRINTING and HP-41 compatibility.

It is important to say that this manual is not complete and I don't want it to be. This calculator played an unique position among HP calculators! Being a scientific programmable 100% RPN calculator, it also had some graphing abilities but was pocketed sized and non RPL (some people as me like RPN, but dislike RPL).

And because there is a free simulator (Free42) that works on Palm OS, Windows and Linux and there are also some emulators (at the moment emulators are only useful for who has a real calculator since HP-42S roms are not freely available). I know some other HP models from the past and the present like 48G, 49G, 28S, 33S, 20S, 6S Solar, 15C, and even a TI-36X Solar, etc, but 42S is my favorite. e) Have the official manual but don't want to read more than 300 pages! Why HP-42S? Because it was a very, very nice calculator and also a powerful one. c) Have a palmtop with PalmOS and want a nice scientific calculator (get Free42) d) Just want to have an idea how 42S was.

b) Got the Free42 simulator and want to know how to use. This manual can interest people who: a) Have a HP-42S calculator and lost its manual. I have a HP-33S and had a HP-48G, but my brother has one and I also use Free42 simulator for PalmOS. I personally don't have a HP-42S (more than U$300 on ebay).

Message #7 Posted by José Lauro Strapasson on 23 July 2005, 9:15 p.m., Re: May I? (was: An alternative HP-42S/Free42 Manual.) Those who already know the stack lifting, enabling/disabling 'nuts and bolts' should take care when reading, but those who do not know the stack and are reading for the first time it might need some experiments to understand it in practice. In this case, his analysis considers that the stack contents are liftted twice, one time after and another time after. In response to message #5 by Richard Garnerįirst of all, I`m sorry taking the priviledge of answering (espero que o José Lauro me perdoe - I hope José Lauro forgives me), but if you consider that the example José Lauro uses in his book is based on the sequence (2 ), then his explanation is correct, meaning he considers the first and last stack contents in one shot. May I? (was: An alternative HP-42S/Free42 Manual.) I look forward to reading you new additions. Iii)The content of line y goes to line z. Ii) The content of line z goes to line t.
