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, and can be saved to a PNG file. Saving as text will probably be provided in a future release.
The 41C and Voyager keyboard support has been enhanced to provide two-key rollover matching the actual calculators. Thanks to John Hogerhuis for his comments and suggestions regarding the keyboard characteristics. I need to verify that the two-key rollover behavior is the same on Classics, Woodstocks, Topcats, etc.; in which case I'll make the same changes for those models.
Some progress has been made on the Windows port, but it still isn't ready. I expect to include a Windows preview release (possibly with less features than the Linux version) with release 0.73 or 0.74.
