RACK42 - A Spreadsheet Application for the DM42

I proudly present version 2 of RACK42 - the spreadsheet application (and more) for the DM42 hardware.

What started as an "experiment" became my favor DM42-application (even if there is IV42).

For more information have a look at
or see a short video at

What's new:
  • Big Math-Package (even Differential Equations can be solved) - see the examples section too
  • Calculator Mode (for those who simple want to calculate without a spreadsheet)
  • Text (File) Editor (with a "virtual" PC-keyboard)
  • ASCII-art drawing program (copy and paste ASCII objects like rectangles or text)
  • HP-35 (try or use an emulation of the legendary HP calculator)
  • 2048-like game (spent some time with the first game for the DM42)

Thanks in advance for any comment, suggestion or bug to make RACK42 more versatile, stable and intuitive.
Have fun!
