I wouldn't want to discourage any of the discussions here about how to run Fractint under a modern OS, in fact I'd like to encourage them. Some folks have invested quality and skilled time with amazing technical experimentation. Just to say that the easiest way to run the DOS fractint on just about any platform under the sun is to use DOSBox. For the supported platforms see: https://www.dosbox.com/download.php?main=1. One caveat with DOSBox or any of the other methods is video mode support. To get the most out of fractint, the environment needs to have high resolution VESA video modes (if not using disk video). For this reason I prefer the so-called DOSBox svn builds (based on the svn source code, but with extensions), in particular the ones at http://ykhwong.x-y.net/, because they have better video support than the stock DOSBox I have even installed DOSBox on my Android phone and run Fractint, that that that arrangement is very usable (I had to install a different keyboard to get anything to work). I know we have touched on this subject before. Not bad that we are revisiting it again now. I'll be interested to see what folks come up with. Tim
