Fractal fans: I'm still here and ready to resume my fractal adventures, but my 21-year-old DOS machine dedicated to Fractint is at the end of the road. I have two other working machines, both running Windows-XP, which probably for video incompatibility reasons will not run the DOS version of Fractint. Is there a version of Fractint that will run under XP and operate similar to the DOS version? If there is, I would appreciate the internet address. I'm sorry to hear about Paul Lee. Jim M.
Long time big fan of the FOTD There is a working virtual machine using FreeDOS on the fracting.org FTP page You can also use the same version on a USB drive and boot one of your XP machines to that USB drive. If you can find someone local that can load the vm into a Virtual Box (free oracle software available for Win 7, 8, 10, Max OS X, and most Linux machines) You can use the image in the Fractint.ova VM to create a bootable USB drive. There is no official support for VirtualBox on XP The other way to run Fractint on XP would be to use DOSBox (also free download) I have had very good luck running Fractint on FreeDOS (by booting to it from a USB drive and by using it in a VM on a Linux machine and on a Windows 7 machine) It also works in a VM on Windows 10 Thanks for all the great fractals!

Jim, Be aware that rotating the zoom box of Richard's Fractint for Windows beta 5 (now renamed Iterated Dynamics -- and still not released for general use) distorts the zoom box contents by a factor of 4:3 and a function of the angle rotated. The zoom box can, however, easily be rotated 90 degrees and show a correct aspect ratio image -- if you follow the 90 degree rotation with manually shrinking the X direction by a factor of 0.75. Note that Richard adjusted the initial default M-set to show its correct aspect ratio. To see the aspect ratio problem caused by rotation: - let the program calculate the default M-set; - zoom in to get a zoom box ~80% of the full window size; - rotate that zoombox ~45 degrees, and - hit Enter to see the non-1:1 aspect ratio result -- the circular M-set bud is no longer circular. I also recall someone saying that they had trouble with the (V)iew command. In place of View, I simply use a different pixel size window/resolution. There's also a bug that is brought to life when using the formula: formulaname=MandelbrotBC3 (also perhaps in other cases) but I discovered what triggers it and created a work-around that works -- if the function "ident" is passed to the formula... I put my work-around, (and a slight speedup) & the assumptions it makes below. I haven't used all that great a variety of Fractint's capabilities in Richard's version, so I suspect that there are a few further anomalies hidden in it -- it is a "beta" release, after all. However, despite all of the above, essentially all of my thousands of images that are variations on your FoTD images -- posted on my web site: http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html were calculated by Richard's version of Fractint. I took great pains to verify that of Richard's Fractint for Windows beta 5 images exactly matched yours before I proceeded with creating my variations. ================================= Hal Lane's MandelbrotBC3 work around: ================================= frm:MandelbrotBC9 { ; by several Fractint users ; ; fn1() removed.

Yes, this version isn't perfect and has some bugs (hence: beta). You can see known issues here: <https://github.com/LegalizeAdulthood/iterated-dynamics/issues> Please file any additional issues you find through github. Personally I don't see the point of continuing to try and make a DOS version limp along. Others feel differently, which is why I forked. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

Some folks (including me) have been very successful running the DOS Fractint under XP. As you suggested, Jim, success seems to depend on the details of the graphics, not on the version of Fractint. Running Fractint under DOSBox works on just about any system, certainly under XP, at the cost of just a bit of setup effort and some reduction of speed. Another strategy would be to boot DOS from a thumb drive or CD. This would also require some VESA utilities to get decent resolutions. DOSBox is likely the most direct solution. The svn version has the best graphics support (http://ykhwong.x-y.net/). Most recent version was a little over a year ago. Other suggestions for Jim? I replaced the floppy drive on my main computer with a double-bay gadget that lets me insert SSDs or 2.5 inch laptop drives (Kingwin Dual Bay 2.5-Inch Internal SATA Tray-Less Hot Swap Rack with Key Lock KF-251-BK). This allows me to boot different environments. Does require SATA. Tim On Thu, Feb 25, 2016 at 11:52 AM, Jim Muth <jimmuth@earthlink.net> wrote:
