SDT 386+

James F. Mayer · Jan 23, 2006

Will Orcad SDT 3.22 or SDT 386 + run on a K5 computer if I can get a 5.25
floppy drive to function so that I could load the SDT3.21? Will I have to
install some version of DOS to do this? I have versions of DOS that start
at 3.3. or maybe earlier

I think it will run under DOS6 (with Win98). Got a licensed copy
around somewhere with all the original manuals.

SDT 386+ will run umder windows 98, as long as it is in
DOS mode. It has some trouble with display drivers, most people
use the VESA 800, or VESA 1024 drivers. Both are a bit buggy,
and show strange artifacts, but you can get the job done.

The install process won't work properly under any DOS version later
than DOS 6.2. The version included with windows 98 has a faulty
batch processor that doesn't correctly evaluate the extensive batch
scripts that orcad uses for installation. Your best bet is to install
under an old version of DOS, and do a copy to your new machine.

That you have a K5 is of no consequence.

The DOS that comes with 95/98/ME is DOS 7.

Remember how DOS 6 got up to 6.22
after M$ was found yet again doing something illegal?

Okay, I must be thinking of Win3.1, then?

Hi,

Both SDT and PCB work OK on a machine using an Athlon XP

2200MHz processor in the 'COMMAND' mode under Windows XP Home SP2
although printing and plotting from it haven't been tried.

I run SDT on a 64 bit Linux machine using "dos box". It works ok. You
have to be careful to look for the real mouse pointer. Dos programs don't
believe in the idea that the mouse pointer can be outside the screen they
know about.

I also know that it runs under windows XP but is very slow. On earlier
versions of windows, the SDT was forced into a full screen mode and given
direct access to the graphics hardware. In XP all graphics operations are
trapped and emulated. I think this is what slows it down. IIRC, you have
to make the box it runs in "win98 compatible". It is clunky but can be
used.

SDT will run under modern processors. I'm using an AMD Opteron with
SDT386+ running Win2k. I've seen it work on XP. If you use Win2k or
XP, you need to run it under full-screen command line. Depending on
something to do with the BIOS, and perhaps the video card, you may be
forced into using a real DOS environment. SDT works fine under DOS6.x
and DOS7.x.

A nice way to go is use SDT under VirtualPC, something Microsoft took
over. VirtualPC allows you to run some other operating system, like
DOS, in a window. This allows you to run SDT under Win2k or XP in a
window and have other programs like Acrobat accessible.

As to video drivers, there has been recent work done on modernizing
the video drivers so you can use VESA mode, resolutions spanning from
640x480 up to 1600x1200. Check out the files section of
http://groups.yahoo.com/group/OldDosOrcad/ for the modernized VESA
video drivers and other drivers. Be sure your video board can handle
VESA graphics. Vesatest.exe and vbetest.exe are good programs for
checking out VESA compatibility.

Thanks for the info.

Hello James,

floppy drive to function so that I could load the SDT3.21? Will I have to
install some version of DOS to do this? I have versions of DOS that start

My 3.22 handbook says it needs DOS 2.0 or later. I ran it for years
under DOS 3.3. Never had a crash. Not one.

It would be a good idea to create 3-1/2" working copy disks. Or CD.
There will come a time when 5-1/4" drives are very hard to find.

Hello Jim,

A year ago I wrote all my 5-1/4" stuff off onto CD's, fearing that day
when the 5-1/4"drive wouldn't spin up ;-)

I went through that process but in 'low-tech' mode 15 years ago, making
3-1/2" working copies. But it's good policy to keep an additional spare
5-1/4" drive in the closet. You never know. Once at a client we had to
dig out really old field simulations. Luckily they weren't on a 8"
floppy as they initially thought but 5-1/4". Whew. And they had a DOS
machine. We just had to rummage a bit to find it.

You can always send it off for copy but that can cost a couple days.

I find the 'modern' storage media less than adequate. Writing CD-RW as
random drives doesn't always work, writing onto a CD-R takes forever and
recently a USB stick that I thought was the silver bullet caused the PC
to do a hard freeze, several times.

Regards, Joerg

I think it will run under DOS6 (with Win98). Got a licensed copy

SDT 3.22 certainly runs just fine under DOS 5.0

The cpu is a 'don't care' issue.

W3.1 didn't come with a DOS . You had to buy both. Typically it would have been
6.22 but I had no trouble running W3.1 with DOS 5.0

Assuming that you are not using it any longer could i interest you in

transferring the license? With any use being on the order of a year or so
apart, and serious (commercial) use being off the list (i would rather make
serious effort to get GEDA and friends running).
