I published the final version of pyILPER 1.8.0 on GitHub.

The most important new features are:

ThinkJet HP2225B virtual printer with high quality PDF output
Full terminal support (keyboard and display) for the HP75. If you do not have such a device, you can easily connect J-F. Garniers HP-75 emulator to pyILPER.

See the release announcement of pyILPER 1.8.0 on GitHub for further details.

pyILPER 1.8.0 is available on the ANACONDA channel by now. A

Code:

conda update --all

should update pyILPER to the latest version. See the installation instructions for further details.

Please mind that pyILPER now requires Python 3.7 on the Anaconda platform. Check the Python version of your installation with:

Code:

 conda list

You can upgrade the Python version to 3.7 with:

Code:

conda install python=3.7

Many thanks to Dave and Bob for supporting the beta tests.

Joachim

Thanks for a great release Joachim, adding HP-75 support in the terminal is awesome.

I had to upgrade Python from 3.6.x to 3.7; it went smoothly following your instructions, but something in the environment has changed. For 1.7.2, I could launch pyILPer from a Windows cmd file, but this doesn't work with the new version. After some digging around, I found a way to do this, though I can't claim to understand all the subtleties of Ana/Minconda environments.

I have a shortcut on my desktop that points to a cmd file located in my pyILPer home folder. That script contains:

Code:

:: Startup script to launch pyILPer

:: Located in pyILPer's "home" folder

::

:: This line activates the miniconda environment, including adding python to the Windows path

:: In my case, I installed miniconda into C:\Miniconda3

call "C:\Miniconda3\Scripts\activate.bat"

pyilper.exe

Very cool, thanks very much once again!

Great Job !!! Thank you very much. Without pyILPer an PIL-Box I wouldn't use my HP71 so often for programming.
Can anybody help me with starting pyILPer from a MAC Desktop?

best regards from Austria

I did it with a one line Apple Script app:

Code:

do shell script "Path to the pyilper program"

Unfortunately I did not succeed to create a macOS compatible icon of the HP-IL logo for that app

Hi,

yes that's a fine solution. Only one problem besides an icon (can't find a pyILPer icon) is that after double clicking it opens the window and then I have to start the script.

Code:

tell application "Terminal"

    do script "pyILper"

end tell

but it runs :-)

EDIT: find the solution: save the applescript as application - then it runs imediatly

Hello Joachim,

Great version! Just updated everything on my side. Smile

The first thing I did was to test the HP-75 Terminal.
It is working, but the terminal polling by the HP-75 make this so inefficient, it's scary.

Thank you very much!

Sylvain

Hello Sylvain,

The KEYBOARD IS implementation of the HP-71 is obviously much more efficient than the HP-75 version. I don't own such a device and had no "user experience" so far with a HP-75 and the terminal emulation.

But iit is fun if you use pyILPER with the EMU75 emulator of J-F Garnier which can run at much higher speed than the original device. This works, because the HP-75 KEYBOARD is implementation does not use service requests.

I was curious to see the HP-71 controller implementation of the terminal mode, so I did the same investigation on the HP-71 that I previously did on the HP-75.
Again, the way the HP-IL system implements the HP-IB hardware control lines makes it extremely chatty on the wire.
