Schematic Entry Tools? (from: Silly Resistor Values)

[Jim Thompson]

Terry,
Oh, the world may be changing, but not that much.

You see, I am all too well aware of the trials and tribulations in
converting over to Orcad or other software. Lets just say I had a
'professional' interest in it!

But, if you are just starting out, or are just a hobbyist, then of
course, you don't have much to loose going over to new software. But,
if you are a professional (and, many of us here ARE professionals!)
then that transition is full of wasted time 'reinventing' the wheel as
you realize that it will take 'x' amount of time re-drawing that basic
filter block into the new software, or having to confirm that the
simulations in the new software match the results of the old software.
A professional doesn't have time to manage two separate design flows,
unless the payoff is much higher than maintaining the old system, i.e.
and order of magnitude or more!

And, if you are a company, and not just a single professional, the
cost/benefit has to be even HIGHER to warrant a change.

And I have around 25 years of archives (on CD(*), plus multiple file
cabinets of paper schematics dating back almost 50 years ;-)... some
in the old original Capture, most in PSpice Schematics. So, going to
a new software would have to show benefits... works pretty much like
my old software AND can import my archives _with_ease_!

(*) I wrote to CD all of my old 5-1/4" floppies several years ago when
I tossed my last machine that had a 5-1/4" drive, then recently did
all my 3-1/2" stuff

Yes, I agree. I loved Orcad in the DOS days, so fast and so easy to use.

Ahh, the old DOS Orcad SDT386 has new life these days. Some folks have
written a Windows display driver for it which works with Win2k up to
Vista.

Not that I'm interested in Orcad these days, but I do wonder how they
wrote the driver, as Orcad was always closed source ?

Not really. I don't know about the video driver because that always
worked, for any PC I've used it on. The generic printer driver was very
much open. You could configure it in all sorts of directions. Heck,
there were even people who modded it so it would spit out a schematic on
a daisywheel printer. They'd just use the dashes and dots plus
micro-stepping. It worked but probably wore out the wheels and ribbons
really fast.

I once loved it Orcad and carried my keyboard templates around with me.

Same here

I agree.

Bollocks. I don't choose to work for someone based on their
willingness to let me hack at Linux. Your attitude is juvenile.

So where do people fit in your ladder of employment and intelligence ?

Decent engineers have no problems finding work. The terminally stupid
live off the government and whine - constantly.

We know you think anyone that is not employed, is stupid, so

1) unemployed = stupid
2) employed = ?
3) self employed = ?

4) unemployable.

Slowman == stupid

 

[krw]

Not at all.

So sad.

Nope, I never kid.
Incredible.


That's too bad for them, and too bad for you.

No, it really isn't. Linux has nothing to do with the issue.

Neither will you or the company you work for, weighed down and locked in
by Windows.

Instead of being weighted down by Linux, and the hacking involved with
that, perhaps.

I guess you're not in embedded, or if you are, your IT wont be supporting
much of anything in the not too distant future.

You're simply being stupid now.

On what basis do you make that claim ?

You don't include any costs other than the PO for the software.
Clearly you haven't a clue.

Spoken like a true Windows user.

I'll use whatever I need. I don't need Linux. My employer would be
*stupid* to support Linux.

Then I suggest you get on with it, because you're boring me here.

No one forced you to join this thread. Bye.

Where I come from, knowledge is power, and learning is called education.

Linux hacking is fun for some, I'm sure, but some of us actually have
to produce something too.

It enables those who are ignorant to increase their value, worth, and
income, but involves real effort, not trite emotive jibes.

Linux has *nothing* to add, in this situation.

 

[krw]

These days, you don't have to be a hacker to find Linux useful. Your
opinion is based on a long-out-dated prejudice.

I see you're still just as stupid as ever.

Since krw has managed to find work, he likes to believe this. It isn't
generally true.

That you live off the government and whine continually? You sure do!
That decent engineers have no problems finding jobs? They don't.
They're still in short supply. ...and no, I've never had trouble
finding work.

It's a false equation.
Hardly.

Employability depends on the society where you
live and a female engineer - no matter how competent - would have
trouble finding work in Saudi Arabia.

Then don't live in SA, dumbshit!

Korean engineers presumably have
the same sort of problem in Japan, and Afro-American enginers had the
same sort of problem in the southern states of the USA a generation
ago. My problem is being 66 years old in the Netherlands. I'll get
away from the Netherlans in a few years, which may help.

Move where the work is, and stop whining!

krw isn't all that bright, and doesn't seem to appreciate my
intelligence (such as it is). I can console myself that I've fooled a
few IQ tests in my time - as has Eeyore - and a few patent examiners
(but then again, so has krw, though his patents are owned by IBM who
had a policy of patenting anything they could to provide valueless
cannon-fodder for patent-swaps to get access to useful patents).

Perhaps not, but unlike you even I can find productive work. Yes, I
have seven patents, so? Unlike you, I don't make a big deal of it.

I once loved it Orcad and carried my keyboard templates around with me.

I moved to gEDA about a decade ago, and have never looked back, gSchem is
so similar to the old Orcad to me in that it looks similar and is
blazingly fast.

I use a makefile with gEDA and when I click on 'make', the netlister
creates the files for the simulator which then runs, or any thing else I
need.

Smooth as silk and a pleasure to use.

Much of the post processing stuff was pretty open. They had a video
driver generator, but that didn't work most of the time.

One of the guys using SDT386 was a program hacker in a previous life.
He used those skills to figure out the hooks to write a generic VESA
driver for any resolution. He released his source code to the group.
Another guy took that work and converted everything to C and wrote the
Windows GUI interface around that code. Pretty amazing work by these
guys.

Some modifications to the component library compiler have yielded some
nice improvements. The only thing I really miss in SDT is support for
hierarchial components. Plus, with the ASCII intermediate net list
that SDT spits out, you can write your own netlisters.
