The Android App from Olivier De Smet the Go21 gives a different answer than the CCE33 HP-21 Emulator does for a particular calculation...the calculation is 3^201, that is 3 to the 201 power...I no longer own an actual HP-21, and I am curious what the answer is on a actual HP-21. I am referring to the HP-21 Woodstock calc...Thanks.

ive only got the cce emulators

classics come up with 7.968420280E95
HP21 7.9683417E95
HP65 7.968420280E95
HP67 7.968419661E95
HP31E 7,968419E95

Different families, different algorithms I suppose

Is that full precision, or rounded to 8 digits? I get 7.968420280e95 on my HP-25, consistent with the Classics, i.e. before the introduction of the "new math" in the later Woodstocks.

HP-10C: 7.968419664e95
Hello!

Dividing by 1e95 shows the same "hidden" digits on my HP-21 as on your HP-25.

Dear oh dear, it seems I missed that bug a long while back.

I must have translated the original code incorrectly somewhere. Tonight, I wrote a small program to do the translation and the HP-21 now comes up with...7.9684203e95

I have posted the new HP-21 download to teenix.org.

Thanks for the heads up zeno333

Thanks for finding anc correcting the bug in CCE33 for the HP-21...I could not figure out what was going on, thought that there was 2 ROMs for the actual HP-21 or something, but could not find anything on that online....Now I know, thanks.

Does the pic code need the same update?

Hi Harald,

Sorry it took awhile to update the PIC code.

There is a new update available at teenix.org.

The PIC will need to be flashed in [ALL] mode and should be explained when the Windows software communicates with the PIC

I had to do a text comparison of the microcode and this was the error that showed up. Not sure how it ended up that way, and even that the code worked at all.

26F 0 -> p if P = 0
287 13 -> p if P = 13

cheers

Hi Tony,

Thanks a lot! I didn't mean to rush you, sorry if it came across like that.

Running on some actual calculators:

HP29C -- 7.968419661 E95
HP15C -- 7.968419664 E95
HP33s -- 7.96841966626 E95
HP50g -- 7.96841966626 E95 (for ' 3. 201 y^x ')
HP50g -- 79684196662762430801634396.... (for ' 3 201 y^x ' in exact mode)

Biggest question is how I ended up with so many calculators!

Just about everywhere else, that's a valid question. Here, not so much...

Indeed. I'm not a collector myself but I have well in excess of 100 calculators and yet that question never ever crossed my mind.

Nothing unusual about that round these parts

That statement can only be true if one assumes a highly unconventional definition of "collector."
And here I was thinking I was strange for wanting a second fx-9750gII, this one to be left unaltered (i.e. not 9860-ised); or a more modern TI. My "hobby"s rather constrained by the fact I've got no real disposable cash, so I use what little I do get for justifying my other hobby, flight simulation. But that's another tale.

Not really. I'm not a collector in the traditional sense because a typical collector is usually very intent on getting a complete collection of some sort, either all the models in general or at least all models of a particular series (say the five Voyagers) or type (say all the financial ones), etc., and also most collectors are extremely eager to lay their hands on some rare models, say a Red Dot HP-35,an HP-94, an HP-46, or an HP-95, ... and also rare HP-41C ROMs, accesories, books, etc.

Me, I don't care at all. I'm not interested in getting a rare model or accessory, or a complete or partial collection, I only get those models I like for the best functionality or looks, and care nothing about the rest. For instance, I paid good money for an HP-67 or an HP-34C but a Red Dot HP-35 or an HP-21 or an HP-80 leave me cold and I'm not interested in owning them.

Same with 41C ROMs (I'm only interested in the Advantage ROM and the PPC ROM, the rest I don't care) and all RPL models except for the the clamshell HP-28S (and that one only for the looks).

So you see, I'm not a collector. At least not a typical one.

Best regards.
