RE: Leonardo meets Emu42
Just updated the KML code today. Because of a different PCB layout from the display of the HP14B to the HP32S, the '0' annunciator on the HP32S wasn't working.
A new Emu42 version with the possibility of using "Load/Save Object..." for HP32S user code programs will follow in the next weeks. The emulator and the KML script are still in beta stage, so you don't find anything HP32S related on my Emu42 web page. |

RE: Leonardo meets Emu42
Nice! I tested it and it works. Seems that the 32SII keyboard include file is compatible with the 32S. Now to hope Plato can join the party.

RE: Leonardo meets Emu42
Thank you, Christoph!
Am I right in assuming that “A” is the model code for Plato in a KML file? (Since the HP-22S isn’t officially supported, it obviously doesn’t get mentioned in the KML documentation.) |

RE: Leonardo meets Emu42
I'm happy that at least a few people are appreciating the Leonardo and Plato ROMs !
Some background on extracting the ROM. On Christoph's site, you can read: " For [low-end and mid-range Pioneer] calculators you need special hardware and knowledge to extract the data from the Saturn bus system, a way, as far as I know, never gone on a Saturn based calculator". So it was considered as "almost" impossible. The 32S is, as I mentioned several times, my preferred every-day calculator rather than the 32SII, and it was a pity that the 32S was not supported in Emu42 due to the lack of ROM. Some weeks ago, maybe stimulated by the SM projects, I investigated how to extract the ROM from the 32S. I used an old 32S, partially working (usual kbd issue) that I opened long ago, and carefully looked at the PCB. Quite quickly I noticed some 10 unused tracks that end to test pads and are not used elsewhere on the PCB. I had the idea that maybe these test pads were bringing the Saturn bus outside, then with the help of some information from Christoph, I was able to identify the function of the test pads, access the internal Saturn bus and read the ROM. And that’s it ! The needed hardware is actually nothing special: a simple Arduino board is well enough. J-F |

As far as the 32SII and 19BII are concerned, only version 1 with fractions bugs (for the 32SII) and an alpha version with bugs from version 1 + a messed-up demo mode (for the 19BII) have been extracted so far. Any hope to extract the latest rom versions ? Thanks and cheers, Vincent |

The 32SII is using a different PCB and IC package, see here for instance, there are no more the so convenient "test pads" and it will be more difficult to probe the IC pins, or even impossible if the test signals are no more routed to the IC pins. But this is something I will definitively try to do. For the 19BII, opening a Clamshell is not as easy as for the Pioneer machines. Although not necessary destructive it requires drilling or sawing the case. J-F |

Thanks very much to:
JFG - for motivation and extracting bits Christoph - for new artwork to enjoy and the updated KML docs. Just when we thought EMU42 could not get much better... --Bob Prosperi |
