The boldface font of the display look somehow strange in the pictures, or is it just me? Is it adjustable?

Yes, but I prefer the bold myself.

It is solved with current firmware update.

I strongly suspect that you had /c set to 3 and didn't know it, because I cannot replicate that error using any firmware version. If you're sure that it was a firmware bug, please share the firmware version number which contained that bug so that it can be verified.

I have received my DM32 last week. I am nearly sure there was this malfunction. I don't know the firmware version.
But it is interesting you cannot reproduce this error with any firmware version.

What does/c means?

The "/c" function on the keyboard (blue-shift, decimal key) is used to set the maximum denominator, which can be any integer between 0 and 4095.
   

If you set /c to 3, you get the results you saw in your example.

See section "5.4.4. Setting maximum denominator" of the DM32 User Manual for more information.

You are right. Probably i Set c/3 . I can reproduce it.
Thank you very much.

You’re welcome but Joe was the one who thought of this somewhat obscure setting. I was looking at the Fractions section of the HP-32SII Manual after you posted your issue but Joe posted his answer before I could finish reading the chapter!

A new firmware update is available for the DM32. It fixes a number of issues and maps the F5 & F6 top-row function keys to the Up and Down buttons, respectively.

A new firmware update is available for the DM32 (V2.05).
It has the following changes:

* Extended Registers (https://technical.swissmicros.com/dm32/d...irect_only)
* New GUI for MEM->VAR list
* New GUI for MEM->PGM list
* New GUI for EQN list
* New GUI for PRGM mode
* SHOW hold functionality (https://technical.swissmicros.com/dm32/d...#show_hold)

For the curious readers that have assumed the DM32 hasn't enough storage (32Sii was limited to 27 variables, A..Z and (i)) this new release provides 900 Extended Registers for each State File, plus 900 Global Registers, accessible by all Active States. Should pretty much end that complaint.

[Vincent Weber]

Well, Bob...
What about the labels?

[rprosperi]

It ain't over 'til it's over.

Still in BETA... although this is a big release, there's more coming...

I know! Just teasing you. Great already to have come that far!

[rprosperi]

That reply now reads more terse than intended... I should have included a smiley on the 1st line to convey the tongue-in-cheek tone it was supposed to have.

Yes, new and interesting things to come....

[Vincent Weber]

Great! That's fantastic work.
I still prefer plus42, I but I admit that DM32 is very sweet and moving fast ?

A curious question since we now have a DM32, a DM15L, and the new HP-15C CE with larger memory options.

Is it possible for someone with more experience than myself to modify the programs that Katie Wasserman posted to calculate PI?
I am curious as to what the new limits would be.

https://www.hpmuseum.org/cgi-sys/cgiwrap...i?read=899

For the HP32SII, this calculates 200 digits, it runs on the DM32 in a very short time.

For the HP-15C CE, it calculates 306 digits in about 15 minutes.

The amazing one to me is the HP-30B program that runs quickly and does almost 700 digits

Here's my guesstimate for the DM32. Katie's 32SII program stored 8 digits in each of the 26 registers A through Z, which was all the storage available on the 32SII (not including the i register which is needed for indirect addressing). The DM32 currently has 1826 storage registers (A-Z, indirect 100 through 999, and indirect -100 through -999). 1826×8 yields 14,608 digits of pi. The program would have to be modified a tad to use the new indirect registers, of course.

EDIT -- I forgot about the statistics registers, which are indirect registers 28 through 33. That makes a total of 1832 registers (not including i) for a total of 14,656 digits of pi.

14000 plus, that's a lot of digits!
Thank you

Quote:For reference, a real HP-32SII takes a bit over 15 minutes for this test.

It took my HP 35S 138 seconds to reach a count of 720. So the full count of 7200 for this test would take approximately 1380 seconds or about 23 minutes to complete. That 6502 CPU core on the HP 35S was really working hard for this test

This refers to a speed test for the DM32 done in June 23. The program for the test can be found here: https://forum.swissmicros.com/viewtopic.php?f=33&t=3537

At that time the execution time for DM32 on battery was about 8 seconds. With power supply attached it was the same. So the beta-software did not take into account the power supply source.
For comparison: DM 42 needed on battery 25 seconds, with power supply attached 10 seconds.

Now, with a first version of final software of the DM32 being there, execution time on battery increased a little bit to 9.6 seconds, but with power supply attached it decreased considerable to 3.1 seconds.
So DM32 on battery is about 90 times faster than the original HP-32SII and 2.6 times faster than DM42. With power supply attached it is about 290 times faster than the original HP-32SII and 3 times faster than the DM42.
