update 12C ? - robertoataulfo - 10-04-2011

There is an update to HP-12C?
Thanks

?? I don't think so, unless you're referring to the "new" ARM architecture (aka 12c+) as an update (it certainly is faster ;-) )

Cheers
Paulo


Re: update 12C ? - Jeff O. - 10-04-2011

Do you mean an updated rom for the 12c+? (12c+ being the unofficial name of the current 12c architecture with two 2032 batteries and the ARM processor.) If so, the answer is maybe. As I understand things (as discussed here, for example), the latest rom for the 12C+ is dated 2009-11-19 (as shown by menu no. 2 of the ON+g+ENTER self tests.) It was developed in a give and take primarily between Katie Wasserman and Cyrille de Brébisson soon after the 12c+ appeared.

How does this new rom?
How do I get it?
The procedure for installing it is equal to WP34S?

I would suggest you contact Tim Wessman through the HP Museum Forum contact mechanism.

Yes, identical procedure.

You should go to http://sourceforge.net/projects/wp34s/files/FlashTool/ and download the most recent Version of MySamBa. It is much faster then SAM-BA.exe. It works for all images, not only for WP 34S.


Re: update 12C ? - Jeff O. - 10-04-2011

Marcus,

What is the compatibility of the new MySambaMarcus with Windows XP/Vista/7 etc.? How about serial to USB converter issues? Seems like these were major issues with SAM-BA, does MySambaMarcus ameliorate them?


Re: update 12C ? - Marcus von Cube, Germany - 10-04-2011

In effect MySamBaMarcus == MySamBaCyrille with very minor modifcations. I cannot comment on compatibility with different brands of adapters of different versions of Windows but I assume that is has less issues then SAM-BA.exe. I'm hoping for feedback.


Re: update 12C ? - Jeff O. - 10-05-2011

Can you remind me of the advantage(s) of MySambaM over MySambaC? In a previous post you mention that it is faster than Sam-Ba, are there other changes? Perhaps it can load a less than 128 kB bin file into a 20b/30b?

I have a PC running Windows Vista with no serial port, and have purchased an FTDI USB to serial converter which claims to have drivers for Vista. I'll give MySambaM a try and see how it works.


Re: update 12C ? - Marcus von Cube, Germany - 10-05-2011

Cyrille's version does not work with flash images that are shorter then 128KB.


Re: update 12C ? - Tim Wessman - 10-05-2011

It also appears to correctly identify COM ports on Win7. Previously none would show up. :-)

This means you can now use this program on any version of windows (just tested it) and I can trash my XP VM that was wasting quite a bit of space on my SSD. :-)

If Cyrille's version did not do this correctly than it's a matter of the compiler (Delphi 2005) and the library (I use Indy 7). My changes to the code are minor, only dealing with the length of the file.
