I played a lot with TurboCalc and it’s files, and checked the fileformat. I still have some very old files from around 1995-1997. An finally a little bit stuff is working.
The second file is my timetable of 2nd semester in university, I printed it out to hang at the door. (yeah, I had color printer back in the days, a termo-transfer printer) As you can see the properties and colors comes nicely to Leu even the Formula, I need to try more functions to see how to convert them to the Leu functions. Of course it’s also possible to save that file again as Libre Office file and load it there. That’s how it looks like in LibreOffice
