Ever heard of the golden oldies? I always think that new is not necessary better than old. This is not to say that every thing new is bad and all old things are good. It all depends on the circumstances.
The mother of all horrors hit me the moment I tried to run my old faithful DOS-based reinforced concrete beam design program with the Dell. I was able to run only 50% of the program before it crashed repeatedly. I had no problem running this piece of software before on Windows Service Pack 1 and 2. Apparently this piece of software is no longer compatible with Windows Service Pack 3 operating system.
Even the the expert from the IT department didn't know how to fix the problem despite adjusting the pc, beam program and cpu settings many times. Shaking his head all he could say was that there was an incompatibility problem between the DOS-based engineering design software and the newer Windows Service Pack 3 operating system powering the Dell.
Nowadays modern Windows based engineering design programs are sophisticated 3D finite-element softwares that can combine CAD drawing with engineering design. However, for simple and one-off beam analysis and design using such tools is an overkill and an extravagant use of computing resource. Unlike the younger generation of engineers who have never experienced any operating system other than Windows this oldie who was weaned on the DOS operating system of a by-gone era has never gotten to like these modern state-of-art sophisticated 3-D design softwares.
In comparison to the modern CAD-based engineering analysis and design software, this old DOS-based program that I have been using for more than 20 years has none of the bells and whistles of its modern counterpart. Its graphics are rather bland, simplistic and unappealing, typical of the old generation of code-based software written for the MS DOS operating system. However it is very fast and easy to operate and perfectly does the job it was designed to do. It does not even require a mouse to operate other than tapping on the keyboard, In fact I have used this piece of software, which you can even run on a floppy to design structural beam elements for many high rise buildings. Over the years because of its speed and user friendliness I have gotten very fond of this old software and simply can't do without it.
Next week I'm sure going to pester the management to reinstate the previous pc with the old operating system on my desk. Other engineers can have the new Dell if they wish. If the program can't run on Windows Service Pack 3, I am quite certain that it will also conflict with Windows Vista and the latest Windows 7 operating system.
