Yikes! XP under VirtualBox just got 131 updates!
by Timothy Wegner 20 Aug '17

20 Aug '17

... to service pack three! So it must be XP gets updated to the point where updates stopped. And to answer a previous (related) question, when I built my various PCs, I would buy a discounted windows disc that says "To use with a new PC only". Microsoft seems not to mind reinstalling on new hardware if the old machine is dead and hasn't phoned home. I have done this various times with different versions of Windows. In any case I had to trouble installing XP in VirtualDisk using the old disc. I did have to phone, but never talked to a person. Just had to type all kinds of numbers. I will attempt to not post any more about XP :-) Tim

Re: [Fractint] Can u run multiple copies of DOSbox (each w Fractint) simultaneously in Win10?
by Timothy Wegner 17 Aug '17

Hal, I am not sure if the setup really requires separate fractint directories as you suggest (and I guess I suggested), but it might. Running multiple DOSBox instances with fractint will take a little experimentation. Might also need separate DOSBox configuration files, I'm not sure. I think just an hour or two of experimentation could resolve this. And by the way, the main reason I recommend the svn version of DOSBox is that it has better VESA video support. Otherwise the regular DOSBox is fine. I have both on my system, and yesterday just quickly ran fractint in both (from one fractint directory). The main problem I had was the various DOSBoxs grabbing control of the mouse and keyboard. ctrl-alt-delete and then cancel restores control of keyboard and mouse to the main windows. As I said, experimentation is needed. I also want to spend a little time with the SDL Fractint.

Re: [Fractint] Can u run multiple copies of DOSbox (each w Fractint) simultaneously in Win10?

Hal asked if multiple dosboxes can be run under Windows. I believe the answer is yes, but some work would be needed with separate configurations and separate fractints. I briefly experimented and could bring up multiple dosbox instances, but there is more to it than that. Tim

Can u run multiple copies of DOSbox (each w Fractint) simultaneously in Win10?
by Harold Lane 16 Aug '17

16 Aug '17

Can anyone tell me if multiple copies of DOSbox can be run under Win10 *simultaneously* -- each in its own copy of DOS Fractint -- (and each using a different CPU core!)? This could be a big "win," as many current computers have generous amounts of RAM and many CPU cores. Fractint also has a built-in capability for dividing an image into multiple parameter files in a highly automated way. I have another email about that coming soon. I'd also like to know if "DOSbox SVN Daum," that Tim recommends, can have multiple copies running simultaneously under Win10. - Hal Lane ######################## # hallane(a)earthlink.net ######################## -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Jason Hine Sent: Tuesday, August 15, 2017 12:46 AM To: fractint(a)mailman.xmission.com Subject: [Fractint] Windows SDL Port Hooray!

Windows SDL Port
by Timothy Wegner 13 Aug '17

13 Aug '17

First a huge disclaimer - Jonathan Osuch has a very demanding job and can only work on fractint a few hours a week, if that. So he can't respond to feedback in a timely way. This is not to say he doesn't want feedback. That said, Jonathan has been working on an SDL (https://www.libsdl.org/) port of fractint that runs natively on Windows, including Windows 10. This effort is hiding in plain site on the website here: http://fractint.net/ftp/experimental/ Just download the SDL*.zip file, dump the contents somewhere, navigate to the fractint.exe file, and run it. The SDL port can potentially be compiled on other platforms, e.g. Ubuntu Linux, but Jonathan doesn't have that working yet. A couple of points. This is a literal port of the classical DOS fractint, not a normal windows application. So the interface looks a lot like the DOS fractint, and is probably hard to use if you are not familiar with the classic version. This is not even a winfract port, which has some windows interface features. This is alpha quality. An amazing amount works but some things (probably a lot of things) don't. It would be interesting for some of you DOS fractint experts to give this a try. If it seems promising, you might consider some systematic testing (might be premature). Since the list is quiet these days, I see no harm in discussing the results here. Probably you folks can help each other out, since Jonathan will only occasionally be able to chime in. Tim

Fractint execution timing.
by John Wilson 13 Aug '17

13 Aug '17

What's a known execution timing for running a Fractint fractal? I'd like to know how my new system stacks up. Please? Installed Fractint in DOSBox on my brand new laptop, which is surprising me with its agility, under 64-bit Windows 7 Pro with a 500G SSD. I was particularly pleased to find that the touch pad does a fine job in moving fractal selections about... smoother than a mouse. My only problem is one which has been with me forever... can't set up PCTOOLS to put saved gifs into the correct directory. I have a mental block on that subject! John W.
