What??? HP's are the best calculators on the market.

Hi, Sorry, I do not want ot confuse anybody. It was a different discuss about calculators and few poeple mention and older HP ( I think it was HP 16 ) and they said that was the last good HP calculator. That is why I was worried . Actually I really satisfied with my ones ( both of them RPN ) especially with the 48G. First I purchased a CASIO color with graphics, almost the top of the line and returned next day. After I both the 48G. Cheers, Peters

I have an HP48G and just love it. I build my own cables too, the connectors on the inside are 2mm which are kind of hard to find, but Digi Key has them. They are also kind of hard to work with. I don't know if it is illegal or not, but I build them and sell them at my school. I have also interfaced the 48g with a pic. I built an A/D for it. It has kind of slow seeing as the data collection is real time, it would faster if I did the data collection then did a serial dump to the HP. NOw I'm just rambling....I guess the point is I LOVE MY HP!!! If that's any help to you. Peter Schultz wrote: {Quote hidden}> > Hi, > Sorry, I do not want ot confuse anybody.

Actually, they may only be actively producing one calculator at the moment, but various sings say that they will be releasing a new one sometime. hopefuly soon. ------------------------------------------------------------------------------ A member of the PI-100 Club: 3.1415926535897932384626433832795028841971693993751 058209749445923078164062862089986280348253421170679 On Sun, 11 Oct 1998, Brian Aase wrote: > > What???

Hi! Even with the lastest high end Casio or Texas calculators, the HP48G and GX remain the most versatile and powerful calculator on the market. their qualities are not (only) based on the fact that they use the RPN rules, but also because they have a powerful processor (the Saturn) lots of memory, a programming language between Pascal and LISP and the possibility to program it in assembler. It's the only calculator I know that can open cars locks and run video games like a gameboy..... Gael Brian Aase wrote: > > > What??? HP's are the best calculators on the market.

open car locks?

Nope, Texas is much better!!!!

I still prefer my Sharp EL9000. It has a 15X4 character display. Does graphing of functions, solves matricies, does the number conversions, has two programming modes, stat data entry, and 26 user memories - each with it's own button. And it prints and transfers data too. Two of my co-workers have these super calculators that can do just about anything, but it takes them 5 minutes to do the calcs because there are just too many features! >From Sharp minds come sharp products.

After I both the 48G. The discussion was about "programmer's calculator" - calculator for computer programmer, not about the "programmable calculator" :-) HP48 is very good scientific calculator, but I am affraid that this calculator lacks the programmer's features like rotate through carry, unsigned - signed arithmetic etc. For "scientific" purposes (mostly sin cos tan ln) I am using TI-92. Not RPN, but good enough. But I would like to buy old HP-41CX if I will fond some in good condition.

For what its worth, I have one too (many engineers probably have). Without going and looking I think it includes - a core memory or two (300 bytes in A4 size area) - a one valve radio control transmitter (galloping ghost?), - several rotary telephone exchange switches (electromechanical using centralised motors and electrically operated clutches, - Ye olde crystal set (adjustable crystal!) - 6CW4 nuvistor (as found in MIG29s? :-)) - Calculator with core memory. - Calculator memory using wire coil as memory. - Originalish IBM PC (clone?) motherboard board with 16K RAM. - Pre OC71 (OC640?) glass transistors. - ZX81 (80?) Much more, but mind grows dim. Must go and refresh memory. What other interesting things are out there in museum boxes Maybe someone should add a PIC or two to keep this not too OT. -----Original Message----- From: Reginald Neale <RemoveMEnealeTakeThisOuTSERVTECH.COM> Date: Thursday, October 15, 1998 10:18 AM Subject: Re: [OT] HP calculator >>I put my TI-30 into my "Museum Box" along with my Timex Sinclair.

Unfortunately, the only people that tend to appreciate these museum boxes are other engineers, or students (the U has some display cases of old stuff). So, I stopped collecting things and just threw them away. I still have a bunch of old motherboards and stuff, kept thinking that someday they might be of good use, but with prices so low, it doesn't make sense to even keep it around. I keep things that might be collector items by the masses....

Hi Andy and others, I suspected that they might use power tubes such as magnetrons, but I never knew that they used miniature tubes such as nuvistors. What is "wrt" impulse radiation? A comment was also made that with such tubes, a MIG-29 might still be able to fight after a near nuclear miss, but an F-16 could only fly. Actually, that F-16 probably couldn't even fly if its electronics were so affected, considering that it is fly-by-wire with an inherently unstable airframe. Don't they shield the electronics from radiation? I suppose that it is not very effective. Also, I would think that tubes would be somewhat susceptible as well due to charge excess build up on the elements/ ionization of the gas inside (if it uses one).

I read an artcle years ago about hydraulic computers.

There are nuclear hardened versions of IC's and transistors. I believe the problem with semiconductors is that radiation impulse flattens out the hump on the junction making the device a conductor (resistor). Of course, I can be entirely wrong about these things!

I think that no modern fighter is inherently stable enough for a safe landing without assisted attitude control (i.e. at least rate gyro systems and controls, or more). So even if it keeps flying it is not very useful anymore. The main problem is, people die slowly vs. electronics when the reason is EMP or radiation. Also, scores of fighters would be totally useless if caught on ground by a nearby nuke outside shelters, even if otherwise undamaged. I don't think that the valve trick serves to protect them mainly in the air. > I read an artcle years ago about hydraulic computers.

Hydraulic 'computers' (more accurately automatons) have seen widespread use in certain household implements, such as automatic washing machines, and watering systems where they do an excellent job. Pneumatic automatons are very ubiquitous in modern CNC and robotic plants. The only serious problems are, speed and interfaceability. It's pretty hard to make a hydraulic computer drive a CRT display, and it had better operate at speeds below the speed of sound in its innards, which is a fraction of the speed of light, but fast enough to move control surfaces way faster and smoother than one can believe. No hydraulic Pentiums are planned for the near future ;) Peter

My friend brought me this chip from former Western Germany). Modem has 1200 Bd and 300 Bd, automatic pulse dialing via relay driven by DTR line. Both units was built in 19983 - 1986 when the "modem" was forbidden word in communist East Europe. Both units are working like a charm till today, with ZX81 and Spectrum, with proprietary assembler programs. The Spectrum program can also transfer files via X-modem protocol.
