Classic is not readily available for Intel Macs (there are semi-satisfactory hacks which make it sort of work). David, ex-W8EZE I remember Word v. 5; now, if you could get Wordstar 3.3 to run on a Mac, that'd be something :-) bob k5qwg |

The last time I ran WordStar in a micro$oft environment was probably around 1991. That's when I cut over to OS/2. Starting around 2002, I started making the transition to linux. All linux now. I keep the OS2 box for nostalgia. 73 Jonesy -- Marvin L Jones | jonz | W3DHJ | linux 38.24N 104.55W | @ config.com | Jonesy | OS/2 *** Killfiling google posts: http://jonz.net/ng.htm |

EZNEC and Linux
Thanks for the info. Since there's apparently no version control or
"standard" version of Linux or wine, I guess it's not really appropriate to claim that "EZNEC runs on Linux using wine". My statement was based on a single report, from someone using wine 0.9.2 with linux kernel 2.4.20-42.9. But even no two Windows installations are the same, so I'm sure this is true for Linux also. I've never purposefully set out to make EZNEC run under Linux -- the market is much too small to justify any but the most minimal of effort. The current state is, as I said, a result of a change made to make it work under Vista, plus one small change to get around an apparent wine bug (it handles the Windows API call WaitForInputIdle incorrectly). I'll continue to make very minor changes if necessary to accommodate various bugs in wine, but nothing major I'm afraid. Roy Lewallen, W7EL Jon Kåre Hellan LA4RT wrote: OK. So the demo at http://www.eznec.com/DemoEXE/EZWDemo40Inst.exe which I downloaded at 2007-02-22 12:43 UTC includes those latest changes? If so, I have to report that it would not run on either of Ubuntu Dapper (April 2006 release) or Ubuntu Edgy (October 2006). In both cases, I removed wine and its config files from my system, removed my .wine directory and did a fresh install of wine before installing the EZNEC demo. With Dapper, I got "EZNEC can't be run on a network from a workstation". I wasn't, but the home directory is network mounted using NFS. The wine pacakge was wine_0.9.9-0ubuntu2_i386.deb. With Edgy, I got "Run-time error '13': Type mismatch. The wine pacakge was wine_0.9.22-0ubuntu3_i386.deb. I'll try Debian Sid later. They have wine 0.9.30. Please don't interpret this as a complaint. Rather, take it as the beginning of a compatibility list. And I'm still hoping that the demo I tested was out of date :-) 73 LA4RT Jon, Trondheim, Norway |

I did not mean to be critical of Linux, I just could not restrain the urge to expose my wish list! That's fine. I was just trying to clarify the position of Linux in relation to Windows. I'm afraid that at times those of us that do advocate Linux are not as clear about it as we should be. It would be fantastic if there was some magic OS that ran everything. Wait a minute! Linux is almost there! ;-) I have played with WinDRM and some of the Antenna book software with Wine. I have also used Morse Runner with Wine and it's great fun. 73, de Nate -- "The optimist proclaims that we live in the best of all possible worlds, the pessimist fears this is true." |

Good clue there Roy. The -42.9 would probably indicate that it is Redhat or Redhat clone. I don't think anyone else uses that extended kernel numbering format. The official kernels are almost always x.y.z, with the rare special minor fix as x.y.z.a. The 42.9 signifies the Redhat patch set applied, which often has nothing to do with official releases, or sometimes it upgrades one kernel partially or completely to another, unspecified, kernel. Redhat kernels are very confusing, misleading, and have there own special bugs. This 2.4.20-42.9 may actually mostly be 2.4.27, 7 versions newer. But you'll never know. The "standard" in Linux is actually the kernel itself. The distributions are the packages that surround the kernel. This includes the desktop and all the other software that comes with the distribution you install. Kind of like the VW bug engine and chassis and tons of parts kits available. Except Redhat insists on changing random parts on the engine, boring a 1600 out to 1950, and still calling it a 1.6 liter. Before I am attacked, I am NOT running down Redhat here. I use Fedora Core 6 at work, and am quite happy with it. As a desktop. As a server platform however, their silly kernel numbering system often makes it very hard to know how their kernel features map to the Linux standard kernels. And when I need to be sure a piece of hardware such as a particular SATA controller or SCSI RAID is supported, I am forced to build a new kernel from scratch from a standard kernel source release. Not hard, just a pain that would be alleviated by Redhat sticking to the rules the rest of the distros (most) stick to. tom K0TAR |

Recompiling Fortran code which has no interaction with the user other than getting text input from one file and writing text output to another is a vastly different problem than re-writing a 60,000 line Visual Basic interactive graphical user interface in another language then recompiling for Linux while retaining full functionality of all features. The difference between the two problems seems to escape a lot of people, but problems do always look easier to solve when it's someone else's job to solve them. Roy Lewallen, W7EL J. B.

I'm sure you're a cool guy and all, but I'm not about to spend a couple of years of full time to do you a favor so you won't have to fool with wine. Sometimes it's just a tough world. Roy Lewallen, W7EL Hello, Roy, and all. I have used a g77-compiled version of NEC-4 on a Linux platform and it worked fine. The GNU compiler works with FORTRAN-77 source code as well as C. I assume a g77 compilation of the NEC-2 source code would also work. Of course this is just number-crunching NEC that does not provide the other bells and whistles of EZNEC.

And free of course... So if someone sits on the VB code for EZNEC, just rebuild it .Mono on Linux BUT LINK IT STATICALLY! This means the code will run on almost all varietys of Linux! //Dan, M0DFI |

Has the programming been held within the confines provided by the original provider' the U.S. government. Who overseas the content of this so called program. If it has a patent then all would or should be revealed in the patent disclosure. Has anybody taken this for his own use for the advancement of science which is the reason for patents? Has anybody upgraded the assigned patent for the sake of science or has something not been disclosed to prevent true examination and as such invalidates the patent? Does the government have the option of review of all algorithms or are they in the same position the country is with voting machines? Basically the purchaser is really in the position of caveat emptor especially since all programs provide different results! Art |
