  • Less strict LIF media header checking when mounting image files.

pyILPER 1.3.1

Introduced IDY frame configuration option.

pyILPER 1.3.2

  • Added LIF image file management functions (export, import, rename, purge, pack, view, label) to the drive tab.
  • Added utility functions to initialize LIF image files and to fix invalid header information.
  • Added navigation controls to help window. Make help window resize able
  • Renamed and added file types for the drive tab directory. All file types of the Online LIF disk project should be considered now.
  • The PILTERM basic program requires Rev C of the KEYBOARD lex file rom now on.
  • HDRIVE1 drive type now accepts arbitrary medium layouts.
  • pyILPER reinstates the previous display position at launch.

pyILPER 1.3.3

  • Added configurable charset for the text file viewer.
  • Virtual keyboard is stable now.
  • The PILTERM basic program does not require a certain revision of the KEYBOARD lex file any more.
  • The PILTERM basic program now sets the delay for fast scrolling.
  • The virtual HP-IL device status was moved to the utilities menu.
  • Scrolling left and right now works for wrapped lines in the terminal.
  • Terminal now supports switching between insert an replace cursor, the indicator was removed.
  • Terminal size, terminal font size and terminal color scheme can now be configured via the pyILPER configuration menu. These settings now also affect the printer and the scope.
  • Improved virtual device status window: shows internal HP-IL state as text.

pyILPER 1.3.4

  • Support for 230400 baud. Requires at least PIL-Box firmware version 2.0.
  • Changed the configuration file format from binary to JSON. It is not compatible to the previous format. Please configure pyILPER again.
  • The device configuration dialog now detects the available COM ports on windows (contributed by Christoph Giesselink). The device detection on MAC OS X was improved.
  • Device clear now resets the printer display.
  • The open file dialog now lists files without extension (bugfix) and remembers the last directory.
  • On Windows the %APPDATA% path is used to store the pyILPER configuration.
  • The baud rate of the PIL-Box device can now be auto detected (contributed by Christoph Giesselink).
  • The IDY frame processing option is now enabled by default.
  • The scope can now be configured to show inbound, outbound or inbound/outbound traffic.
  • The scope log file is now written without buffering. This slows down file output but you can now watch the file output with external commands.
  • The terminal, printer and scope windows are now scrollable. The scroll buffer size is configurable.

pyILPER 1.4.0

  • The script startup.py now accepts a parameter -instance INSTANCE-NAME to start multiple independent instances of pyILPER. Each instance has its own configuration file. Only letters or digits are allowed in an INSTANCE-NAME.
  • New device configuration facility to add or remove virtual HP-IL devices or to change their tab position. If a new device is added you must give it a unique name. Since the configuration file format was changed in this case, you have to re-estabish a previous custom configuration.
  • In the initial configuration of pyILPER, the printer is the first virtual device now (as in the original ILPer) to avoid MANIO issues with the HP-41C.
  • New virtual HP-IL device: the HP7470A plotter! Note: at least version 1.7.6 of the LIFUTILS must be installed to make use of the plotter.
  • Configuration dialog for the plotter pens added.
  • Redraw the screen when the application window was resized (bug fix).
  • Use wcat41 instead of wall to display wall files (bug fix).
  • Allow mounting LIF image files with directory not starting at record 2.
  • An experimental new version of the PILTERM utility (PILPERM2) to set up printer, display and keyboard of the HP-71B.
  • New release notes and getting started documents.

pyILPER 1.5.0

  • Improved stability for virtual HP-IL over TCP/IP.
  • New PILTERM version 2 is default now. You find the old version as PILTERM1 on the PILIMAGE.DAT image.
  • Transition to Qt5.
  • The font size of the drive directory listing can now be configured. The row height of the directory entries are now properly adjusted to the font size.
  • Improved online manual. The position and size of the manual browser is recorded in the program configuration file.

pyILPER 1.6.0

  • The number of lines of the printer, scope and drive directory output is adjusted to the size of the main window automatically.
  • The output window of the plotter is adjusted to the size of the main window maintaining the aspect ratio of the papser size setting (see below).
  • The terminal, printer and scope now support copy selected text to the system clipboard. The terminal supports paste text from the system clipboard.
  • Most pyILPER configuration parameters that control the GUI layout now take effect at runtime. Only the scroll up buffer size and the paper size require a restart of the application.
  • The pyILPER configuration dialog now informs if configuration changes issue a reset of the communication or require a restart of the application.
  • The previous size of the pyILPER main window is restored on start of the program.
  • The HP82162A printer is now included as virtual HP-IL device.
  • Barcodes can be created from the context menu in the drive tab for HP-41 program and SDATA files.
  • Directory listings can be created from the tool menu in the drive tab.
  • The paper size option was moved from the plotter configuration to the pyILPER configuration in the file menu. It controls the paper size of PDF output, the plotter paper size switch and the aspect ratio of the plotter output window. A reconfiguration is required if the letter format is used.
  • The terminal size configuration parameter was replaced by the parameter terminal width. A reconfiguration is required.
  • The scope got an option to display the frames as hex codes.
  • Added mouse screen scrolling support for terminal, scope and printer output window.
  • Various bug fixes of the terminal.
  • The ROMAN8 character set now includes control pictures for most of the C0 control codes (code 0-31).
  • Improved diagnostics, if the configuration file is corrupt.
  • The address of a reenabled virtual device is reset to zero, if a HP-IL device addressing operation took place while the device was not enabled.
  • Version 1.7.7 of the LIFUTILS are needed.
  • The detection of LIFUTILS installations was improved. A path can be configured to use LIFUTILS which were installed at non standard locations.
  • The PILTERM utility was updated to version 2.1. This version deassigns any DISPLAY IS, PRINTER IS and KEYBOARD IS assignments before issuing a RESTORE IO to avoid possible data corruptions.
  • The default pyILPER configurations now puts the virtual drive tabs at the end of the tab menu and therefore at the end of the virtual device chain.
  • Added a PIL-Box emulation by means of a TCP/IP socket server.

pyILPER 1.7.0

  • Virtual device widgets can now be undocked from the tab into floating windows.
  • The configuration of a device tab/window is now implemented as cascading menus.
  • Pixel size of HP82162A display is now configurable.

  • Allow smaller font sizes for the directory listing and the terminal widget.
  • Added the --clean startup option to clear an existing config file.
  • Added the "paper" colorscheme
  • Various other bug fixes, see the internal changelogs. This change makes the log files compatible with other programs linke the LIFUTILS

pyILPER 1.7.1

  • Disabled the automatic shrinking of parent widgets. It caused unpredictible results on virtual device reconfiguration.

pyILPER 1.7.2

  • Extend the ASCII file import of the virtual drive. Distinguish between an import for the HP-71 and the import for the HP-41 wich needs special handling.
  • Check the minimum required Python version on start of the application.

  • Added local controls to the terminal tab to scroll up and down one page. This required minor changes to the HP-71 keyboard layout (see below).
  • Terminal emulation bug fixes.
  • Various documentation amendments
  • The most recent version of the PILTERM program is now 2.3.
  • The minimum required version for Python is now 3.5 instead of 3.4. Features of Python 3.5 and above make the code for calling external applications more clearly and easy to maintain.

Incompatibilities to previous pyILPER versions:

    Due to the introduction of the HP-75 character set the configuration of character sets in existing pyILPER installations must be adjusted if the Roman-8 character set was used.
