Wp34s base mode question - Cristian Arezzini - 05-18-2011 I'm still "playing" with the emulator, waiting for the cable to arrive so that I can reprogram my 30b (by the way, I'm sort of liking the 30b even before reprogramming! Is there a place to download the original 30b firmware, so I can flash it back should I want to?)
On the 16c, if for example you set 2's complement, and 8 bits word, then the numeric entry is interpreted "on the fly": i.e. if I am in base 10 and try to enter 254, this is what happens: I press 2 and the display shows "2"; I press 5 and the display shows "25"; I press 4 and the display shows "-2" because 254 doesn't exist in 8-bit 2's complement, but its bit pattern represents a decimal "-2". Second question: I noticed that the current version of the emulator (1.17 build 874) still has the hexadecimal "E" bug - i.e. if you enter E by itself (or as a last digit), it is ignored and a 0 is entered instead. What's the status of that bug? Will it be fixed in a new emulator? Or, is there a way to tell the emulator to use the latest firmware? Third, unrelated question: Does anyone know if there is a way to have the 16c integer base capabilities (especially with respect to settable word size, and carry/overflow bits management) with the 50G? Either natively or with some additional software?
Thank you, Re: Wp34s base mode question - Marcus von Cube, Germany - 05-18-2011 Cristian, V1.17 is frozen with all its bugs. You can get 1.18 from the SVN repository. The emulator is in the trunk/windows/bin subdirectory. This is "software in motion" and may be broken at any time. If that's the case, SVN allows to retrieve older versions.
The emulator does not use the actual flash file as it does not try to emulate the hardware. It uses the same software base (written in C) but is compiled with an MS compiler to produce a Windows executable.
Re: Wp34s base mode question - Cristian Arezzini - 05-18-2011 Hi Marcus,
Thanks again, Re: Wp34s base mode question - Marcus von Cube, Germany - 05-18-2011 The question has to go to Pauli who wrote that stuff. I don't believe that he will implement the life interpretation because wp34s has an internal command line which gets interpreted only when some function is performed. So the interpretation needs to be implemented directly in the input editor.
Your assumption about the modulo interpretation makes sense to me.
Re: Wp34s base mode question - Paul Dale - 05-18-2011 Yes, we do the input modulo the word size. No, I'm not planning on changing the way numbers are input. The sources are freely available, so feel free to send us a patch :-) Marcus is correct about the input going into a command line buffer. It should be possible to process the command line on keyboard entry and do what the 16c does.
Re: Wp34s base mode question - Cristian Arezzini - 05-18-2011 Thank you both for your replies! :)

Re: Wp34s base mode question - Neil Hamilton (Ottawa) - 05-19-2011 I too am waiting for both my cable and my new HP30b to arrive. I am very willing to sacrifice my current HP20b -- especially since there seems to be a replacement F/W image in the HP SDK -- but I might like to revert the (yet to arrive) 30b back to its native state. Does anyone know the answer to Cristian's question about restoring the original HP30b F/W? Is it available from HP by special request or can it be downloaded from the calculator? BTW: My 20b F/W has a checksum of 130 (copyright 8 01 2008) whereas all the examples I have seen online have different checksums. Does anyone know what F/W versions are out there? What version is in the SDK?
Cheers...
Re: Wp34s base mode question - Marcus von Cube, Germany - 05-19-2011 HP 30b firmware is available from Tim Wessman on request. I can't give any information about existing versions.
There is no way to read out the flash through the serial connector. In order to get into SAM-BA mode, you'll need to erase the flash first. After this, the original firmware is gone. In wp34s, I've added a command to just clear the boot bit and boot into SAM-BA. This preserves the flash contents. To my knowledge no such feature exists in the original firmware.
