HP-189 Subject: Why does everyone like the 48g series so much? I was just curious as to why everyone likes the HP 48G series so much better than the 49g (48gII/49G+ also). I'm a college student, and I had a 48G+ that my brother gave to me a while back. The keys were really nice, but the problem was that the calculator was SO SLOW. Seriously, there was no point in even using the MSLV/equation library because it took forever, and was faster to do by hand, and numerical integration was faster by hand also... I bought the HP49G+ recently. I can tell that the keys are worse than the original, they have a hollow sound and are pretty loud, but if i push the keys in the corner, they're pretty quiet. (Also, I remember I left a heavy book on top of the calculator while it was in the black case for about a day; the buttons were really good and made no sound, but after 4 hours or so, the buttons went back to normal). The HP49G+ is also WAY faster than the 48. Graphing is fast, and the MSLV is also pretty fast. My complaints of both of the calculators is that there is no TABLE function, where you can see a table of values of a graph. Also, when graphing, there is no way to type in a value, such as 3 (for x) and get the respective Y value. (Unless I'm stupid and can't find these things) Also, what's up with the price of the 48GX, in the past week, I've seen 2 on ebay go for 110 (buy it now ended) with just the soft case... === Subject: Re: Why does everyone like the 48g series so much? > I was just curious as to why everyone likes the HP 48G series so much > better than the 49g (48gII/49G+ also). If you use it for practical problems you want something rock solid and reliable. There have been complaints about the HP49 in terms of keying in data that must be regarded as serious. Also as a practical matter the HP49 offers little that the HP48 doesn't already have.

It is faster, yes and the CAS is nice I'm sure. However that will not help you for student sized problems. In an examination I doubt you will find time to 'type' in complicated equations and complete your problems in the time allowed. Particularly when you consider that most instructors require shown work. Also as a 'student' numerical integration is rarely an acceptable answer except for special projects so I see little benefit here. Professionally I 'might' numerically integrate on my calculator, howeer I'm more likely to use PC software. It's more powerful, the interface is better and I am better able to integrate the results with other tools (to make reports, generate additional analysis/results, etc.) > I bought the HP49G+ recently.

Graphing is fast, and the > MSLV is also pretty fast. Graphing is nice ... and for a student it might be fairly useful, however my experience is that if you're sharp enough to quickly graph a function and get the display set-up to be useful, you were sharp enough to get it 'approximately' graphed by hand. If you can do that, then what did the graphing function offer that you already couldn't do? Afterall you still had to key the equation in. If I had to complain about the HP48-49 series ... I prefer the 'clamshell' arrangement of my old HP28S. It was MUCH faster for entering programs and data. With proper selection of function layout it would also kick booty for programming over anything a 48/49 could offer. === Subject: Re: Why does everyone like the 48g series so much? > I was just curious as to why everyone likes the HP 48G series so much > better than the 49g (48gII/49G+ also). The 48G (and 48GX) are better built. The keyboards are excellent and the older ones still have molded keys. I have used a 48GX for 10 years or so with no problems. It has always been able to do what I needed. It got me through a Master's degree and through many years of engineering work. Basically, it is solid and reliable.

Number one: Because it works reliably with none of the problems that exist in the later HP models. Their quality went down the drain starting wit the 49G and has gone down hill ever since. Any more questions?? Rod === Subject: Re: Why does everyone like the 48g series so much? The HP49G+ is way better than the old HP48 series in almost every way except quality and durability.

The 49G+ seems pretty solid to me. Not as rugged as the 48, but i suppose if you don't go fiddling around with it its not going to break. Should I keep my 49G+? I'm doing industrial engineering and so far, haven't really used it much. I'm sure i could get by with a 33s (the new HP scientific with RPN), or is the 33s not good (not many posts about it). I could probably sell the 49G+ for about 90, and go buy a regular 48g, this is my last year of calculus, so i probably don't need the speed increase or extra features that i (might?) not use. === Subject: Re: Why does everyone like the 48g series so much? > The 49G+ seems pretty solid to me.

Good point:-) Indeed, HP48 come to me (and I think that to many other of us) when I was student (1994) so there was a lot of thigs new to discover and to look for. Now as a professional (and about 40 years old) needs force me to work and make money, much more than programing HP48 like I used to do when I was in the college. New HPs should be used also in professional areas, but now I use more PC than it. HP calcs was a very good tool when I was a student, but now as a profesional I think it is not so good as used to be to me when I was a student.

A good idea. I'd like a low-cost shirt-pocket sized (Voyager series sized, at the most) RPN calculator. The only ones in current production are the 12C, 12c platinum, and maybe the 17bII+. But those aren't exactly low-cost, and all three are financial models. I'd prefer scientific models. A very low-cost, very basic four-banger RPN model would be very welcome.

That would be interesting. As far as I've noticed, the 49g+ doesn't have any new *UserRPL* commands over the 49G, and I expect that Jean-Yves will be able to do any bug fixes required on the 49G ROM.

How so? The hardware will be different, but I suppose that anyone interested could have fun discovering how to do it, just as they're currently doing with the 49g+, and with many calculators before, for that matter. -- === Subject: Re: Qonos- A Future Failure? Yes, i agree cracking it will be as much fun, but let's assume ARM9 will be emulated and Saturn up on it, it will all work nicely if they go for 100% emulation currently Saturn is amulated in the 49G+ (as we all know) but screen updates, beeper and similar features are not updasted real time -the emulation is not 100% result: we have functional units, but we lost some features based on fast hardware programming switching, tweaking and so on :) Therefore Qonos migt turn out to be in a separate class (if they don't go for 100%) but on the other hand they might produce a very well 49G, then, with time, once they manage the ARM emulation which i agree will be interesting to see they might get 49G+ which would actualy be better than current 49G+ firmware. Let's hope HP decides to release a ROM update with better 49G compatibility. if 49G+ had just a bit more pixels it would be peace of cake to emulate TI. You could load apropriate ROM and enjoy your favorite calc.

Note that SysRPL entry points were moved and new (or changed) UserRPL and SysRPL commands were added in each model change from 28C to 28S to 48SX to 48GX to 49G, and at least sometimes even in revisions of the 49G ROM. Why should we expect the change from 49G to 49g+ to be so much different? Or from the 49G to the 49G emulation on the Qonos, for that matter? I'd prefer that no attempt is made to emulate the bugs new to the 49g+; any left over from the 49G would be enough. I do hope that a ROM improved from 1.19-6 can be used. > Therefore Qonos migt turn out to be in a separate class (if they don't go > for 100%) > but on the other hand they might produce a very well 49G, then, with time, > once they manage the ARM emulation which i agree will be interesting to see > they might get 49G+ which would actualy be better than current 49G+ > firmware. You mean that they should emulate the ARM hardware too? Why on earth would they want to do that? It seems to me that another layer of emulation would slow things down, use up more memory, and present yet more opportunities for bugs. I suppose that it would give the hackers more things to play with, but for ordinary users, remember that May you live in interesting times. is supposed to be a curse. And I think that Hydrix might have a bit of a legal problem if they tried to distribute the 49g+ ROM image without HP's permission. But of course, HP would have a bit of a problem trying to stop 49g+ owners from using a ROM image that they just happened to have available, if someone came up with a way of loading it. Maybe they should simply provide emulation software for every processor ever made? Of course, feel free to emulate the ARM (or any other) hardware yourself. New 49g+ features that I'd consider worth emulating on the Qonos: USB and IrDA, but with proper handshaking before printing and XMIT, and proper flow control, and a reasonable range for the IrDA. The larger screen, but able to use the full screen height better. But the last that I read about it, the Qonos is already supposed to have more pixels in both directions. I hope that Hydrix plans to put all of those pixels to good use in the HP calculator emulation mode. But maybe each calculator pixel will be displayed as a 2X2 square on the Qonos? 48 series features missing from the 49g+ worth emulating: RS-232 compatible I/O, including software flow control. Serial IR I/O, compatible with the 48 series. Red-Eye IR (for 82240 compatible printers) restored to a reasonable range. I expect that Veli-Pekka would add some more.... Come to think of it, the Hydrix site says HP48/49G, so maybe we'll have our choice of 48SX, 48GX, or 49G. :-) But hey, what about the 28 series? I wonder whether the emulated Saturn is close enough to the Lewis to run a 28 series ROM image. > Let's hope HP decides to release a ROM update with better 49G compatibility. I'm hoping for a new ROM release too, although I've begun to wonder whether they've already abandoned the 49g+ to work on the next model.

The one I was at seemed to be the most popular (lots of links to it from other pages). All the threads were either game requests or debates on whether or not people (teenagers) should be allowed to play games on their calculator during class. I've never been as proud to own an hp as I was that day. --CS === Subject: Re: Ti 89 Titanium basic questions > I'm not sure if that's the same TI NG I've been to, but I was very > disappointed with one of them.

If HP calculators had a large market, I'm pretty sure this newsgroup would turn into a Help! This game doesn't work! group. Not that there's anything wrong with playing games. I play games occasionally on my calculator and my (home) computer. -- === Subject: Re: Ti 89 Titanium basic questions Hi Tom; Mostly ignorance on my part. Have a good one.

EXP2HYP 'VPN' - it is Complex, isn't it? === Subject: Re: Laplace transform issue of 49g+ Yes, turn the Complex mode on or run LIN before LAP could solve LAP(SINH(X)) and LAP(COSH(X)) question. Invert Laplace have to be transform the answer to back to SINH(X) and COSH(X). Thansks for your help. I doubt that how many 49g+ users could understand using it with it's manual... I found that even 49G's manual is better than 49g+'s. Now I'm using 49G's manual to learn 49g+. I waste $22 to print the 49g+ manual out. === Subject: Re: William Wickes, Larken Publications ? > Are any of the HP48 books by Wickes still available?

As I understand it, Larken is formed from the first parts of his two children's names, Lara and Ken maybe? Anyway, it wasn't a big publishing house; I guess that it published his books only. He never did publish the planned Part II of HP 48 Insights HP 48G/GX Edition; maybe it wasn't profitable enough, or maybe he just didn't need the extra money. I believe that he transferred to a different division of HP when the calculator division was moved from Corvallis to Singapore, so maybe it was a lack of enthusiasm for continuing his project.

It was laying on a desk and I pushed the keys with one of my index fingers - entereing half the numbers I intended to incidently. *Snap*, and the black rim came clean off broken in two. It must've been the case flexing slightly to make that happen. It's apparantly way too brittle. So, now I ship the sucker back to HP for a refund - I'm done with that sh**. it's much faster for the work I do anyway... === Subject: Re: Well, now my HP49G+ is finally falling apart > Hi. > The black fender thing around my HP49G+ suddenly snapped while I was using > the calc.
