HP-67 image

In mid-November, Xavier Théry contributed a very nice HP-67 image. I’ve just adjusted the KML file and checked both into the Subversion repository. It will be used in the next release.

Nonpareil progress

There hasn’t been much to report on Nonpareil development lately. I haven’t had much time to spend on it, but I have made some progress. Most notably:
I came up with a scheme to fake the Woodstock pointer wrap behavior well enough that the HP-29C and HP-67 label search code works. I don’t [...]

A Nonpareil user asked about keyboard mapping for the 41C/CV/CX ON, USER, PRGM, ALPHA, shift (gold), SST, and R/S keys. All keyboard mappings are user-configurable in the KML file, but setting them properly is tricky. Until now, you had to know GDK’s host keyboard keysym number (called “scancode” in the KML file), and [...]

I was astounded to discover that I was voted best speaker at the HHC 2005 conference which wrapped up today in Chicago. I gave two presentations, one on the last year’s work on Nonpareil, and one on the calculator prototype Richard Ottosen and I have built.

Maciej Bartosiak emailed me a new set of PNG image files for the Voyager calculators (HP-11C, HP-12C, HP-15C, HP-16C) which look even nicer, so they will be in the next release.

Spice calculator ROMs

There were some ROMs shared between the 67 and 97, and between the 19C and 29C, which is not surprising because those were pairs of printing and non-printing machines that were otherwise nearly identical.
And there are certainly many code similarities between various models.
But I was surprised to discover that the Spice series has some large [...]

Nonpareil on Windows

Nonpareil now runs on Windows, as well as Linux and other Posix platforms.
Nonpareil is cross-compiled from Linux using a GCC cross-compiler targeting i586-mingw32msvc.
There is not yet an installer; it’s just distributed as a ZIP file. It appears that I should be able to use NSIS to create an installer, and still do everything from [...]

Nonpareil 0.72

I just released version 0.72 of Nonpareil which is the first release to include the 82143A printer support I mentioned here last week. Graphics and custom characters (BLDSPEC) are supported, subject to the same limitations as a real 82143A (42 byte buffer size). The printout is shown in a separate window at two selectable sizes, [...]

There’s some bug that prevents the printer simulation from working on my Fujitsu Lifebook subnotebook (800 MHz Crusoe processsor), but I haven’t yet had a chance to try to debug it. It works fine on my other machines, aside from the problem I noted yesterday with use of the Paper Advance button when the [...]

Interesting bug

I added buttons to the Nonpareil printer support for the “print” and “paper advance” functions, and radio buttons for the MAN/TRACE/NORM switch. I’ve posted an updated screenshot.
There’s an interesting bug. When the calculator is not in PROGRAM mode, the print and paper advance buttons behave mostly as expected. In program mode, the print button works [...]
