I've recently got myself a '95 workstation OpenGL acceleration card that's using an Evans & Sutherland Freedom chip. It came with the drivers for WinNT 3.51, but I'm trying to find drivers for WinNT 4 or Win9x if they exist at all. So far I've tried Archive.org and Google Groups, but came up with nothing. Archive.org only has copies of es.com site from 1998, where Freedom is not even mentioned.

I've tried installing the WinNT 3.51 drivers under WinNT 4.0 Workstation, but it said that the drivers are incompatible.

Does anybody have any relevant files or info on this card?

Worst case, could always contact Evans & Sutherland, or submit a support ticket on their website. Worst they can say is "Sorry we don't support that card anymore" and you'd be stuck with NT3.51.

Might have to fudge some contact details on their ticket form. I wonder if they'd accept "Personal Use" as planetarium name.

Well, you definitely have a point 😀 Sent them a ticket.

Would have emailed John Carmack — he seemed to have had an Evans & Sutherland card in his Dolch PAC machine in 1998, and logically it should have been a Freedom, but others have already tried, and he doesn't even remember the model of the card.

I was wondering if you might have managed to get this unique piece of hardware up running in an NT 3.51 or later environment by any chance?

I tried looking for a Freedom Graphics card several years ago unsuccessfully but accumulated more knowledge than leads in the end. There is not a lot of information surrounding this card, aside from a couple of reposted E&S press releases providing hardware specs and characterizing it as a ‘cut-down’ Freedom Series graphics card for the PC market – an April 10, 1995 InfoWorld magazine piece states E&S’ intention was to transform a PC into a mid-range Silicon Graphics workstation.
Freedom Graphics was initially showcased during Fall Comdex in 1994 (November). The card was scheduled for a release sometime around March 1995, after a delay the last mention of a launch was August of that same year – I am not entirely sure when or where the card made it to market. The card got a bit of press coverage in the context of VR during 1995, the hardware was exhibited with one of E&S’ in-house game demos called Midnight Manor. PC Magazine’s March 14, 1995 edition (p183) briefly discusses the cards capabilities in a paragraph alongside a picture of what seems to be an earlier version of your Park City board.

E&S’ 1996 fiscal year report reveals the company was experiencing issues during the mid-90’s: fierce competition in several markets as well as restructuring (i.e. reductions in all business groups). According to this report, sometime in 1995 E&S eliminated the entire Freedom Series product line, because it was not profitable. Hardware and software support seem to have continued across the various platforms and operating systems for some time – judging by the documents, press releases, and announcements put out by DEC, HP, IBM, and Sun.

Thank you for reaching out! Don't have any good news, unfortunately.

Well, I did try several things, but so far I haven't been able to find newer drivers.

- contacted Evans & Sutherland. They've responded by saying they've long sold the graphics business, but someone might have some archives in Collins Aerospace office in Salt Lake city. I've tried looking for people who worked at E&S on LinkedIn, sent some requests — no luck.
- like you, I've tried looking for vendors that shipped their computers with E&S. DEC's site isn't available on Archive.org, HP.com is semi broken. I did manage to find some mentions of HP Vectra workstations using E&S cards, but it looks like they used later REALImage cards, not Freedom. AFAIK, IBM didn't use E&S on x86 machines.
- talked to some professional graphics cards collectors, but I haven't found anyone with a Freedom in their collection, let alone drivers for it.

I've got my hands on a cheap Intel PR440FX motherboard yesterday (dual Pentium Pro). Pretty useless thing for games, so I might as well turn it into a Windows NT 3.51 workstation once I find some EDO-DIMM memory. Too bad 3.51 can't run any OpenGL games (that I know of), but there is no guarantee that Freedom can run Quake, either.

The Mario 64 PC port can be compiled to run with OpenGL.

Well I managed to build the "normal" port to Windows 98 😀 (it also works with NT4 and even 3.51 !)
This time it needs opengl to run instead of glide. It ran well on my riva tnt2 m64. I'll try to run it on my SLI using mesafx.

HP FTP archives exist on archive.org . Unfortunately, there are no content listings. If you are motivated enough, you could download them and look for drivers .

According to this press release, Win9x drivers was planned:

Evans & Sutherland Freedom

PRESS RELEASE

:

"EVANS & SUTHERLAND BRINGS 3D GRAPHICS EXPERTISE
TO THE PERSONAL COMPUTER

SALT LAKE CITY, March 2, 1995
Evans & Sutherland Computer Corporation (NASDAQ: ESCC) today announced
Freedom Graphics(tm) for the Personal Computer. Freedom Graphics is
the first product to bring the 3D graphics technology of E&S to the
personal computing environment.

Freedom Graphics is an implementation of the specialized features that
3D graphics applications require for smooth, fast execution. Users
can produce impressive realistic images with the product's rich
feature set and high-performance graphics for Windows/NT(r)
applications.

The graphics card supports the OpenGL(r) software application
programming interface and is designed to accelerate OpenGL in the PC
environment. Freedom Graphics is a PCI bus-based card that
incorporates the same technology as the Freedom Series graphics
accelerators which supply high-end graphics for the world's largest
workstation vendors. Ideal markets to take advantage of the extensive
feature set of Freedom Graphics are CAD, Industrial Design,
Simulation, Visualization, Animation, Entertainment and Game
Development. Supported PC processors include MIPS(tm), Pentium(r) and
Power PC(tm).

"The interest being generated by Freedom Graphics is extraordinary,"
said Jim Oyler, President and CEO of Evans & Sutherland. "Freedom
Graphics allows a low-cost PC-based system to achieve the performance
of a much more expensive workstation. This is going to be an
explosive market in the very near future."

Evans & Sutherland is the only 3D graphics vendor with a product line
that spans the entire computing industry from the personal computer up
to multi-million dollar flight simulators and location-based
entertainment systems.

"We are pleased that Evans & Sutherland has applied their knowledge
and experience in high-performance real-time 3D graphics to the PC
marketplace," said Tom Coull, President of Sense8 Corporation.
"WorldToolKit and Freedom Graphics will offer a definitive
hardware-accelerated solution for texture-mapped virtual reality
applications."

Freedom Graphics' feature set includes real-time 3D graphics rendering
and animation, hardware based 24-bit texture acceleration, scalable
texture memory up to 16 MBytes, bi-linear and tri-linear MIP-mapping,
specular highlights, fast set-up calculations, full scene
antialiasing, transparency and depth cueing. The additional
experience of E&S with OpenGL will also result in significant
performance advantages for applications using the OpenGL library from
E&S.

According to Ian Reid, Vice-President of Marketing at Advanced Visual
Systems, "Freedom Graphics offers a new level of capability for the PC
user and AVS/Express allows any PC developer to take immediate
advantage of features such as hardware texture-mapping and
transparency. It's the ideal combination."

Freedom Graphics performance under Windows/NT and OpenGL is 300,000
triangles/second. The card will list price at $2450 with second
quarter availability through OEMs and VARs. Freedom Graphics was
first shown at Fall Comdex '94 in Las Vegas.

The significance of Freedom Graphics lies in its delivery of a
graphics feature set at unsurpassed performance levels. Advanced
features such as texture mapping are still unavailable from any other
vendor for under $10,000. Freedom Graphics also provides performance
not yet seen in the 3D PC graphics market. Nearest competitors for
performance provide minimal feature sets and are only available at
much higher prices.

Evans & Sutherland is a leader in advanced 3D graphics and
visualization systems for science, industry, education, and
entertainment. The Graphics Systems Division provides graphics
hardware and software solutions that are sold and supported by DEC,
HP, IBM, and Sun Microsystems. Evans & Sutherland was founded in 1968

Product details:

Freedom Series Graphics from Evans & Sutherland
HIGHLIGHTS

* World's fastest graphics system now available on AlphaStation
workstations
* Extremely high performance 3D graphics supporting sophisticated shading,
lighting, and texturing models
* Upgradable, scalable graphics performance spans a range of prices
* Packaged in a separate deskside chassis
* Exploits Digital's new, industry leading PCI64 interface; also supports
standard 32 bit PCI

PRODUCT DESCRIPTION

The Freedom Series graphics from Evans & Sutherland, the world's fastest
graphics technology, is now available on AlphaStation workstations.
Providing both dominating performance, as well as new capabilities, such as
texture mapping in hardware, Freedom Series excels in applications such as
visual simulation, high-end mechanical design and styling, and high-end
geographic information system applications like petroleum reservoir
modeling.

Freedom Series offers raw power plus superb image quality. Advanced graphics
features include anti-aliasing of points, lines, and polygons to eliminate
the stair step raster artifacts. Shaded image display capabilities combine
speed with both shading and lighting models. In addition to doing the
familiar gouraud shading at incredible speed, Freedom Series provides
advanced lighting models for more realistic images. Freedom Series graphics
provides a 24-bit Z-buffer, as well as an 8-bit Alpha buffer to support
transparency effects.

Freedom Series also supports in hardware a technology called texture
mapping. Texture mapping involves taking a texture, such as wood grain,
brick, or even an entire tree, and mapping it onto a surface. Texture
mapping produces extremely realistic images that begin to approach
photorealistic images--images that are indistinguishable from a photograph
of an actual scene. There are several algorithms used for texture mapping.
The simplest algorithms produce raster artifacts, similar to the jaggies
from lines. There are several ways of improving image quality and
performance, and the leading algorithms for this use are tri-linear
interpolation and MIPmapping. Freedom Series graphics supports both of these
capabilities in hardware.

Freedom Series is targeted at the AlphaStation 600 and the AlphaStation 250
systems. On the AlphaStation 600, Freedom Series uses the PCI64 bus to
provide a full 64-bit high bandwidth interface between the AlphaStation and
the Freedom Graphics module. The Freedom Series graphics also supports the
standard 32-bit PCI interface used on the AlphaStation 250.

Features of the Freedom Series include:

* Extremely high performance
- Up to 4 million 3D anti-aliased vectors per second
- Up to 4 million shaded polygons per second in triangle strips
- Up to 800 thousand gouraud shaded polygons per second
- Up to 320 thousand texture mapped polygons per second
* Smooth motion

Seems also IBM included the Freedom cards in their RS/6000
workstation line (unix, risc based):

Show full quote

IBM offers OpenGL 1.0 at several different price and
performance points, on most configurations of it's RS/6000
workstation line. Hardware accelerated OpenGL is available
through two recently announced products: the mid-range
POWERgraphics GXT1000 and the high-end Freedom Series /6000.
Both platforms provide h/w support for texture mapping,
accumulation, stencil and alpha buffers, as well as a h/w
accelerated lighting and geometry transformation pipeline. The
Freedom Series is based on an architecture developed by Evans
and Sutherland.

All this info is from Google Groups. I cannot find any info that Windows 95 or Windows NT 4.0 drivers were actually released. Only references to Windows 95 says they are planned.

If you're searching for the HP products, Freedom seemed to be included in the "HP 9000 Series 700 workstations with Freedom Series"
https://web.archive.org/web/19970414133518/ht … ucts/715ds.html
Seems those workstations didnt use Windows NT/x86, but HPUX

It seems to me that these cards were only sold by OEMs into workstations (Sun Solaris, IBM AIX, HPUX, and DEC's.) and thus there were no reason to further develop Windows NT and Windows 95 drivers.

Also, please upload the drivers you got to Vogonsdrivers, or attach to this thread.
