However, the 15C CE can hold several large matrices using that data space just not “data memories”

The limitations of extended versions (w/ more the 99 registers) are already known for the SwissMicros DM15L, but having them all in one place here may be convenient:

Major limitations:
- inverting a matrix, or calculating the determinant, or solving a system larger than 8x8 gives wrong results, or may crash the machine.
- it is not recommended to enter more than 999 program steps (no crash but possible weird effects after step 999). Especially step 1000 is displayed as " 000-000000"
- the GTO CHS sequence to reach a particular program step can't go beyond 999.

Minor limitations that just give an error message:
- you can't allocate more than 99 storage registers,
- you can't create a matrix with more than 99 elements in a row or column:
i.e. you can't do 120 ENTER 1 DIM A
but you can do 60 ENTER 2 DIM A to get a matrix with 120 elements.

If other limitations are known, please share !

Is the CPU in the 15C Collectors Edition the same as the CPU in current 12C models?

Is it the same as the earlier Limited Edition models?

Has anyone checked the known bugs list from the Limited Edition? Are they resolved, hopefully, without introducing new ones?

The old HP12c+ (until 2015) and HP15c LE had an AT91SAM7L128 processor. The cable to reprogram the unit was RS232 to custom POGO connector.

The newer HP12c (from 2015) and HP15CE have a SAM4LC2CA processor with much lower battery consumption. The cable is now USB to same custom POGO connector, so it is NOT the same cable (although it can be converted from the original with a no-way-back method)

The known bugs were fixed but of course there may be new introduced!

My HP 15 CE is scheduled to arrive on Monday, 8/7. I'm encouraged by all the good news that I'm reading so far.

The dates from the 1.L 2.C 3.H menu:

HP 15C LE: 2011-04-15
HP 12C: 2008-06-28 (overdue for an upgrade?)

[Divasson]

The last paid orders have been packed and will leave early Monday. 705 orders but 937 calculators - many getting 2 or more units.

I see that shipping has improved a lot - the time to destination, even to overseas customers, is getting shorter and shorter. In many cases, customers in France and Germany got the calculator 1 day after handling it to UPS or SEUR.

Many thanks José for all this. i received mine on Wednesday perfectly packed.

Thank you, I believe I have collected at least one each of most generations of th 12C, including 2019, and 2021 manufacturering dates, so should have a matched set.

The new ones are so much faster than the originals!

Does anyone in the US have an example of how long it took to get yours?

I'm getting impatient waiting for the US distribution... I may be doing some convalescence in a couple of weeks and it would be nice to have a new toy to play with to keep my mind occupied.

So, normally super-frugal johnb is debating ordering from you guys.

Hi, all,

Self-quoting:

(08-03-2023 07:08 PM)Valentin Albillo Wrote:  I'll post tomorrow or the day after that (i.e. Saturday Aug, 5th) a couple of HP-15C programs I've written which can be used to compute the matrix inverse and the determinant of an NxN matrix (2 ≤ N ≤ 16 depending on available RAM,) [...]

I'm just completing the docs, including several worked examples, so stay tuned.

Done. Find it here.

Best regards.

Initial notice of shipping on 07/28, DHL delivered on 08/03 to the Metro New York area. So very little time in transit after customs approval.

From The Calculator Store, Barcelona.

Shipping took only three days to get mine via UPS from Oxford Educational Supplies in the UK. I received it eight days ago.

Took a few days to Germany, but the CE was worth the wait. Thanks to everyone who made it possible.

Still, it's nice having the extra space... it feels... good.

Well, someone here once said that the 15C was a single-program machine. That might change with the extra space. I already have 3 standard programs loaded on my DM15.

Nice, but I seem to overlook something obvious here: what keys are the L, C and H? What do I press exactly here?

1.L 2.C 3.H is the main test screen.
Press 1 to perform the LCD test;
Press 2 to perform the checksum test and see the firmware revision
and copyright messages;
Press 3 to perform the keyboard test.

There is nothing about «press 4», it is secret function

L C and M represent the tests.

1, 2 or 3 start the corresponding self tests.

Two questions (if they have not been already answered):

1. Is the PSE (pause) bug fixed?

2. Is the multiple combination (Cy,x)/ permutation (Py,x) bug fixed?

1. Yes.
2. Yes; instead of the display going blank or blinking, "running" is correctly displayed now. EDIT -- Not true. Eddie Shore found some examples of COMB which result in a binking display without overflowing. Details here: https://www.hpmuseum.org/forum/thread-20...75665.html

got my parcel from Spain today :-) I opened the package containing serial number 262 (an interesting number for an aviator, although I am not so much interestested in military stuff, but still...). The other one I leave untouced for the time being, if the serial number are consecutive it is eiter #261 or #263 (prime). Let's wait and see how long I can withstand the urge to open it and have a look!

Look and feel are perfect, no bad "f" and "g" keys or other flaws. And it smells very new!

Many thanks to all who make this possible!

Regards
Max

Finally got mine despite the massive DPD f*ck up which delayed everything by almost a week. I got #109 which goes very well with yours Maximilian And yes, I am into airplanes too. What do you fly?

Serial numbers were not consecutive in my case. My 2nd one is #174. Now which one do I use daily and which one do I keep as a spare/collector? (I'm sure to lose some sleep on that question )

Here too perfect quality, no f/g flaws or anything. Only strange thing, the protective foils were attached to the windows of the boxes, not to the calculator. Not sure if it was intended that way, but I'll sure not loose any sleep on that.

And yes, absolutely happy with my purchase. Well worth the wait. Next step, a HP-16C with HP-15C mode?

[johnb]

Boy, when folks said post-COVID shipping times have improved A LOT, they weren't kidding!

Thanks guys!

I just received my HP-15CE (L/NO. 9CJ323) (s/n: 01062)
Shipping : 4 days : (Friday) Spain → Italy → UK → Canada (Monday)
