Hello,
does anybody has information if there are different 32sii rom versions?
If so, is there any way to check it?
Regards
Axel

Hallo Axel, because nobody replies to this posting I want to tell the minor what I know. - does anybody has information if there are different 32sii rom versions? Sorry no information about this. - If so, is there any way to check it? Another difficult question. I had a look into the ROM image symbol file I have and found no hint about a label or function that has something to do with version handling/printing. 2nd I had a short look into the disassembled code of the key waiting routine inside the <ON> <Y^X> single step selftest mode. I had found no key dispatcher which would allow calling other functions inside the single step display test. BTW, the HP32SII ROM image has a size of 16KB and is fully programmed in assembler. That means no RPL code inside. Regards Christoph

It seems there are different ROM versions. If you look at Craig Finseth's HPDATA (http://www.finseth.com/~fin/hpdata.html) at the end of the file about 32SII some known bugs affecting fractions are mentioned and he says HP offered, back then (1991), a trade in to exchange the bugged machines for upgraded ones. ▼

That's correct. I just tested "2) The "Fixed Denominator" mode" with a ROM image and with a real HP32SII from 1999. The ROM image shows the bug, my real one not -> different versions. Christoph ▼

I have a real 32sii but I'd like to add the 32sii to my virtual collection too. What can I do, Christoph?

Just curious: How did you extract ROM image from the real HP-32SII?

Eloquent answer. ▼

If it would be a marketing piece the picture would be a fake and/or the pay button is missing. But why the pay button is missing? I haven't the rights to distribute any ROM images and to answer another question an extraction from a real calc isn't possible. An emulator without ROM images is useless and will only cause requests for ROM images on differents forums (ie. HP28C ROM images for the published Emu28). It makes no difference if the calculators are in production or not. We should be glad that HP gratefully allowed us to make ROM images from our personal calculators to use them in emulators. Emulators never dammned by HP. So what about the ROM images that are available (list not complete): HP38, HP39, HP40, HP41, HP48, HP49. The following list is my personal opinion, be free to have your own one. Let us begin with the oldest one
Another final words to the free available emulators Emu28, Emu42beta, Emu48. Some people think they can get all for free without any payback. Payback don't mean money in all cases. I personally also use free software, so my development on HP emulators is a sort of payback for there work. But in the last time I invested many of my free time on emulator development and that's the most important thing, much money to buy the original calculators, first to get a legal copy of the ROM image and 2nd without the original calculator the emulator development is very very difficult, even if you have some documents about the hardware (BTW, TNX to Paul Courbis for his picture of the HP28C memory layout). This is also one of the reasons why I don't publish a fully working non beta version of Emu42. 1st I hate questions for ROM images, 2nd I invested to much time and money to give it away for free.

Christoph,
Having said that, I might add that I do not believe you can turn this emulator production into a business. I learned from Luiz (I met this guy from Brazil in this USA forum 8-0 ) that by trading (without using money) you can have lots of fun, make interesting friends, and have access to things that would not be available to you otherwise. Luiz taught me how to create good-will among strangers and remote friends.

Hi Renato,
I think Christoph has shared many things with the HP-48 (and relatives) community. Without his hard work, Emu48 would be still next to useless, as it was before Christoph took over. Regarding the additional emulators, I think it's also a matter of copyright. It makes no sense distributing an emulator for a ROM which you definitely don't have access to;-)

Christoph, I just want to weigh in here and say thank you for your work on emulators. When I first discovered the various emulators a few months ago, I was totally astounded.....it was wonderful to see the old computer culture--with the spirit of cooperation and sharing--still living on!
