Hi all,
I am trying to install AutoCAD R12 for Windows 3.1 on a
Celeron 766 with 64M of ram running DOS 6.22 and Windows
3.1. The SYSTEM ERROR
Divide by Zero or Overflow Error
Why am I getting this and how do I fix it so the program will run?
thanks,
charles.....
I seem to recall that there were a number of programs that did not
like high speed processors and needed the processor speed to be
throttled back to avoid divide by zero errors.
Do some searching along these lines to see if you can find a solution.
This particular computer has no way to underclock even if that is the
sollution. The computer that I am trying to "fix" was a DX2486-66
with 16M of ram and a 1.2G hard drive. Turns out that lightning hit
it and the ps and mb are fried. I take that the best recommendation
it to find another 486? How could companies write code like this?
thanks,
charles....
I seem to vaguely remember that in older versions of autocad there were
some compatibility issues with non-intel processors.
Since the processors are here to stay, this was fixed in subsequent
versions.
Well, autocad 12 was written long before the processor you're running
was made.
If you want up top date code for up to date equipement, get an up to
date version.
Once you take away a whole bunch of bells and whistles from newer versions
you are still left with a great deal of the capability which does most of
the drawing required in my discipline (architecture) in R12, and I have to
assume that it uses far fewer resources than some of the later versions. R12
was FAST. R12 for DOS was even *FASTER*.
Because of backwards capability, newer versions will have no trouble with
his files. If Frank owns this thing, his cost per drawing is tiny compared
to those firms who always have to have the latest version, whether or not it
makes sense. Frank could buy himself a very nice new TV for the difference,
and still afford to have us all over for the next Superbowl or World Cup,
and supply all the beer....maybe even the pretzels
agreed, most of what has been added since R14 has been toolbars and
different ways to access what was already there. I guess the learning
curve is a consideration if you have 100 seats AND IF the buttons make
it easier on a new cad operator. but for me, upgrading the operator
takes away time from production.
I'd rather write a little lisp....
but even more important to this old fart is that once I get something
set up the way I like it I don't want to change. go figure.
I used to use Telix for BBS communications and it had a problem with
the processors with speeds in the hundreds of MHz. In those days
programmers were actually constrained by available memory and unlike
today where they tend to write sloppy code, programmers tried to get
every last bit out of a system. With speeds around 66 MHZ, it was
wasteful to consider speeds in the hundreds of MHz when there were not
even a twinkle in the eye of developers.
Unfortunately the best solution is to get another 486 motherboard. It
might take some finding but like parts for vintage cars they will be
around.
Hello and thanks for your answer.
I can understand this point of view. I still use Autocad rel.12 to create
IGES models to import into Ansys. I really liked my Autocad 12 when I used
it. I think they also add some new good features in new releases, not only
superficial things. Unfortunatly I use 3rd part applications that need
Autocad in a recent release. And this made me spend more money but made me
make some more money too.
I just wanted to know what is the pourpose of using a old version of
Autocad. No offense.
My puor english doesn't put me in the position of understanding the sottile
meaning of this. I love soccer, though... :-)
Ciao ciao

None taken. I didn't say that there were no significant improvements in
later versions of AutoCAD, just that the older versions like 12 would still
do the majority of what I do typically. My feeling is that many (not all) of
the "improvements" of late are superficial.
I just tried to say that you can use r12 and others with newer versions can
still read your files. (The problem is the other way around.) Also if you
don't spend thousands of dollars every year or two for new software because
you can still use your old software, you would have more money to spend on
other fun stuff.
PS You English is so 'poor' that I didn't know it was not your first
language until now ; )
