Change Log(*) Change Log(*) DETAILS Version 0.8 (2012-May-20) * The emulator now implements more of the conditions described on page 21 of the 1614P Instruction Manual, concerning how and when floating truncation takes place, and what is displayed for overflow. * The emulator now as an Edit->Preferences dialog box, for changing some aspects of how the emulator is presented. Version 0.7 (2012-Jan-10) * Antonio Arias discovered that the Makefile.in file was missing all of the entries needed to install the PNG files needed by the GUI. This has been fixed. Version 0.6 (2012-Jan-09) * Antonio Arias discovered that one too many "gui" path components were added when searching for .png files for the custom widgets. * A bug has been fixed in the management of transparency of the card reader window. The use of Gtk::Window::set_opacity was wrong, it makes the whole window, including the contents, transparent. Instead, the window needs to (a) have an RGBA visual, and (b) set the background to transparent. Version 0.5 (2012-Jan-07) * The canola(1) program now includes a card reader animation, with an overlayed undecorated window. If a compositing window manager is used, it will be transparent as well. * The dot down the left hand side of the program listing has been removed, because the real Canola 1614P doesn't print one. * The canola(1) command is now able to save the data memories as an assembler program file. This can be useful when producing cards sets of constants, as seen in the GF series of cards in the Program Card Package. * The canola(1) command now has a more faithful replicas of the Power Button, the Program Selector Switch Program Mode Switch, and the Rounding Switch. * The canola-card-scanner(1) command is now able to look for the rows and columns of holes by itself, making it more able to cope with slight differences with image scanner DPI settings and alignment. * The address field in the Debugger pane can now be modified by the user. This is helpful when debugging jumps. * The canola-asm(5) man page now has details of each opcode. * The Program Card Package (included with each 1614P) is now complete, the final MS-18 to MS-25 subroutines have been added. Version 0.4 (2011-Dec-30) * There is now a PDF of the Canola project's Reference Manual on the web site. * The Program Card Package now includes MS-7 a**n, MS-8 a**x, MS-9 10**x, MS-10 log10(x), MS-11 exp(x), MS-12 ln(x), MS-13 sinh(x), MS-14 cosh(x), MS-15 tanh(x), MS-16 asinh(x), and MS-17 acosh(x). * The Program Card Package is now available on the web site, as example software, linked from the Documentation page. * The canola-card-scanner(1) program now also understands JPEG image files, in addition to the PNG files it understood previously. * Hans Dorn reports that the START keys is ignored in LRN mode, and now the emulator conforms. * Hans Dorn reports that the $710..$715 opcodes cause an overflow and display 9999999999999999, and now the emulator conforms. Version 0.3 (2011-Dec-24) * The Test Run Program still does not perform correctly, so there are still some instruction set subtleties that have yet to be discovered and addressed. There are many new questions in the questions.html file on the web site. * The MS-3 to MS-6 card sets are now included, in addition to MS-1 and MS-2 previously. * Thanks to scans provided by Markus Brenner , the Statistics ST-1 to ST-4 card sets are now included. * A bug has been fixed in the handling of the EJ instruction. It was not correctly detecting whether or not the user had entered data. * Thanks to scans provided by Markus Brenner , the Group Function GF-1 to GF-4 card sets are now included. * The program load and program save dialog boxes now start from the current directory, rather than the Recently Used list. * The emulator now include support for using the [UJ] key when in [OPE] mode, to cause execution to start immediately from the indicated flag jump. * Chris Baird contributed his prime number program, and his quadratic equation solver. * The error dialog is no longer modal. If more than one error happens before you can click "OK" then all of them will accummulate in the secondary text area. * Hans Dorn discovered that the real 1614P isn't very fussy about the key following RM3~ (et al). It simply uses the lower 4 bits of whatever key you press. * Markus Brenner responded to the "Questions" page on the web site with answers to many of the questions, and those answers have been incorporated. * The file menu entry Program Card System now throws up a dialog if you don't have it in LRN mode. You can still choose OPE, but the default is LRN. * Chris Baird discovered some build prob- lems with the latest version of libpng, as they phased out some long- deprecated struct accesses. * There is a new canola-card-printer(1) program for drawing Canon Canola 1614P card images. It can draw them as PDF, PNG or SVG. It can draw the classic "blue" cards, or the blank green ones, etc. Version 0.2 (2011-Nov-27) * The state machine controlling the calculator's arithmetic and opera- tor precedence has been extensively tested and improved. * A unit test for MS-1 (sin) has been added, and another bug in it has been foxed. * There is a new debugger pane. It displays the register values, the memory values, and when a program is executing, it shows the source code with the nect opcode to execute highlighted. * The test suite has been supplemented with examples from the 1614P Calculator Instruction Manual. * The [K] key (constant mode) is now implemented, for both multiplica- tion and division. * A bug in the SM opcodes has been fixed, they were storing into the wrong location. * The Program Print key on the printer is now permitted in Program Mode OPE. Version 0.1 (2011-Oct-27) * Program Mode Switch now supported for all modes. * Retro widgets now implemented for all keyboard buttons. * Most opcodes are now implemented, including jumps and subroutines. Some opcodes still have subtle problems.
