![]() ![]() Here you can find emulators for HP-42S (very nice) Try asin(acos(atan(tan(cos(sin(6°)))))).įor more information about HP-42S please see If you want to download the fantastic Thomas Okken Free42 program please go to this web site my opinion Free42 is even better than the real HP-42S. This because I suppose most ownersdon'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 reallydon'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 programmable100% 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) thatworks on Palm OS, Windows and Linux and there are also some emulators (at the momentemulators are only useful for who has a real calculator since HP-42S roms are not freely available). I know someother HP models from the past and the present like 48G, 49G, 28S, 33S, 20S, 6S Solar, 15C, andeven a TI-36X Solar, etc, but 42S is my favorite. Why HP-42S? Because it was a very, very nice calculator and also a powerful one. e) Have the official manual but don't want to read more than 300 pages! 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. I have a HP-33S and had aHP-48G, but my brother has one and I also use Free42 simulator for PalmOS.Ī) Have a HP-42S calculator and lost its manual. I personally don't have a HP-42S (more than U$300 on ebay). Other operating systems: The latest Free42 version from 2023 is also available for Mac.Since HP-42S was a very nice calculator, and its official manual is no longer freely available andthere were many people looking for its manual, seemed good to me to write my own HP-42Smanual. It comes in both 32-bit and 64-bit downloads. Previous versions of the OS shouldn't be a problem with Windows 8 and Windows 7 having been tested.
