Sun CG12 / GS aka Matrox SG3-1152B graphics accelerator for 3D solid applications - Page 1

Some pics of the GS CG12 (cgtwelve) 24-bit integrated accelerator and color frame buffer from 1990 for SBus-based SPARCstations (1/1+/2 and 5?), partitial manufactured by Matrox Electronic Systems, Canada. Used as affordable 3D desktop graphics solution. Placed between the CG6 (2D/3D wireframe, higher 2D perf) and GT (3D solids, higher 3D perf) graphics. Anounced with the SPARCstation 2GS, Nov 5 1990 (Src: The Florida SunFlash).


Installed in the SPARCstation 1+ (Sun-4/65) with plenty 16 MBytes of RAM.
Ultra short snap of the card running in OPB. Yes, black and white only with console. Not so under SunView and OpenWindows.

FIrst run with SunDIag 2.3.3 tests under SunOS 4.1.4 went all fine
(unfortunatelly only a photo of the screen)
A GFX tape comes with the GS for SunOS 4.1.1. GFX still needed for SunOS 4.1.4? I think the tape including SunPHIGS, SunGKS, SunVision and XGL developer libs (headers etc). - Unfortunatelly not in my supply. :(

Code: Select all

Fully functional graphics:
- 24-bit true color
- 12-bit double buffer
- 16-bit Z-buffer
- 8 additional planes for overlays and windowing
- Gouraud shading with up to 8 lights
- Depth-cueing, hardware picking
- Multiple rendering modes

2. Graphics software:
* XGL runtime bundled on every system.
* SunPHIGS 1.3, SunGKS 3.0, SunVision 1.0, and XGL for developers
all orderable.

4.1.1 GFX:
(...) The GS also requires the installation of
the 4.1.1  GFX tape.  This tape will be bundled in with the GS for both
the SPARCstation 2GS configuration and the upgrade. This means that the
customer does *not* need to order this tape as a separate line item.
(...) The GS will run without the 4.1.1 GFX tape, but will be
*SIGNIFICANTLY* slower and less reliable.  Make sure this tape is
loaded.  There are only a few files contained on this tape and
installation instructions are included. Installation should be under 30
minutes.

Unfortunatelly only the infos within the code block of the former post.

There is a white paper " SPARCstation 2GS / SPARCstation 2GT Technical White Paper ", but nobody seems to have a copy.

If you want to compare it with solutions of other vendors, e.g. with SGI, HP/Apollo, IBM, DEC or highend PC's, look after workstation solutions dating back to late 1990 (Nov, 5 = anouncment of the SPARCstation 2GS). At least there will be differences between the used graphic APIs. This entry-level solid graphics sub-system with 24-bit color depth capability is optimized using the Sun XGL and Pixrect/Pixwin API libs .
Depending on the level of optimization within the graphics pipeline (implemented through device handler/driver), there are some functions accelerated in hardware other in software (host CPU). But for sure, the sub-system is by far less performant if used for ordinary/all day windowing operations (RasterOps), for which e.g. a CG6/cgsix is the better choice. Of course, also heat is a serious point here.

The example picture with the starship Enterprise is only wireframe, not a solid model. Anyway nice.

For creating something simple (some "simple" solids) you need also the development headers of the libs, which were sold separately with SDK (Solaris Software Development Kits).

Noticed it? One board is manufactured in collaboration with Matrox Electronic Systems. For each of the colors red, green, blue there is one dedicated DAC chip (BT).

Some history about Matrox graphic solutions

Matrox products in the late 80's until late 90's offered always the option for stacking base boards with upgrade options for gaining more sophisticated graphic features. So the products could be offered for price sensitive customers as for performance users searching state-of-the-art graphics hardware for high-end PC-based workstations.

Assuming the older naming scheme of vintage Matrox products was kind of...

Code: Select all

<bus_type>-<max_(h)resolution>
So I guess Matrox SG3-1152 standing for " S -Bus or "SUN G raphics", "3 SBus slots or 3 D" (?) and "max horizontal resolution of 1152 (1152 by 900 pixels)
My investigations included requesting the technical support of Matrox but with minor success, because for the SG3-1152 there is no technical staff around anymore and documentation is lost or hidden (proprietary). But I found some articles in archives, e.g. BYTE Mag, PC Mag, InfoWorld Mag, CompWorld Mag.

Some older Matrox Graphics products and solutions, incomplete, in non-chronological order as follows:

QG-640 ( Q -Bus G raphics, max 640 px horizontal resolution)
PG-640 ( P rofessional G raphics for ISA 16-Bit Bus)
SM-640 ( S olid M odeling enabled PG-640 with stacked add-on board)
PG-1024 and SM-1024 (TI34010/TIGA-based coprocessor using DRAM + ASIC-based graphics acceleration using VRAM, max resolution 1024 by 768 px)
PG-1280 and SM-1280 (TI34010/TIGA-based coprocessor using DRAM + ASIC-based graphics acceleration using VRAM, max resolution 1280 by 1024 px)
PG-1281 and SM-1281 (TI34010/TIGA-based coprocessor using DRAM + ASIC-based graphics acceleration using VRAM, max resolution 128 0 by 1 024 px, revised and improved board version of PG-1280)
VG-1152 ( V ME-Bus G raphics, max resolution 1152 by 900 px for e.g. SUN VME-based workstations and servers Sun-3/Sun-4)

Compared to Sun's GS the MG-3D line of accelerators are similar but sold directly by Matrox for PC workstations.

Yes I can confirm Matrox support for legacy hardware is erm... not great.

After sending 3/4 emails to a support guy (who has worked there for 12 years) the lines just went dead and the returned they favour by spamming me information on their latest graphics cards ( because I'm clearly interested in those after inquiring about a product form 1987 o.0).

A part of me is quite interested in Matrox and their early foray into '3D' hardware. I do have SM-1024 and PG-1281 and can confirm you findings. I wonder if I remove my add-on board from the SM-1024, could I turn my PG-1281 into a SM-1281 :) One day when I have enough guts and enough fun with it in its current 'shipped' configuration. The first SM-640 I've seen was manufactured mid-1987 ( viewtopic.php?t=16730932 ), and mine August 1992 (although SM-1024, so later series). Any more info on these would be great. :)

afaik, there was no GL driver (or GL layer/lib.. IrisGL for that matter) that could be used with them (PG/SM PC cards that is), as I think IrisVision was the first to bring anything hardware related to x86) but they all support CGA instructions and PGC instructions (which I think was the first hardware standard to include 3D functionality (albeit executing the instructions in a non SIMD way :) on x86).

Interestingly, my SM-1024 has an 'EGA in' DE-9 male connector and a 'VIDEO OUT' female DE-9. So it can possibly be used as a pass-thru for something else?

PHIGS and GKS drivers are available (so interesting to see what was available on SUN with the Matrox boards), and there are apparently PGC drivers for AutoCAD and a few others. I would dearly love to see some PGC code (I have the PGC IBM manual) since although there was a standard, I think even then manufacturer's were pushing with their own instruction sets because some of the features of what the SM-XXX cards can apparently do, are beyond the scope of PCG instructions. Which gives rise to the question... What did use this extra hardware, and what API's were employed for the job? Does anyone here have experience with PCG/PGA (Professional Graphics Controllers)?

It's nice to see some results on screen, I'm worried that in order to see anything remotely unique (outside of CGA/EGA display) it would involve me either sourcing some hard to find proprietary software or documentation and examples to code so demos too. Latter preferable, but both equally unlikely :(

P.S The SM/PG-640 are 8-bit ISA. later ones 16-bit ISA.

VGA passthrough?

spiroyster wrote: What did use this extra hardware, and what API's were employed for the job?
applications like AutoCAD, Microstation under DR- or MS-DOS. In most cases the graphics co-processor was an TI 34010, later models with TI 34020. So TIGA API (Texas Instruments Graphics Architecture) was used.

spiroyster wrote: ... hard to find proprietary software or documentation and examples to code so demos too.
software - no, e.g. AutoCAD 1x and drivers for your card but documentation unfortunatelly yes. I found some manual from Matrox about the QM-640 which is in fact the same architecture like the PG-/SM-640.

spiroyster wrote: P.S The SM/PG-640 are 8-bit ISA. later ones 16-bit ISA.

I have to find some architecture info about the MG-3D Ultra for comparing them directly with the GS / CG12 / SG3-1152.

There's a compiler and assembler on the wayback machine for the 34010... gcc 2.5 based so pretty old but also much smaller codebase than modern gcc might be of interest to directly program the TMS340x0 on there.

Mmm ... anyone here w/ a copy of package SUNWxglh in version 3.1 for SPARC (XGL Include Files - Headers) also included in the " Solaris 2.4 Software Developer Kit " (CD-ROM) or some developer enabled version of SunPHIGS for SPARC? The package SUNWxglh was later included in the Solaris install media starting from release 2.5. Not sure if XGL version 3.2 (Solaris 2.5) is backward compatible for use with Solaris 2.4!? I should give it a try. The problem is that the GS is not supported under 2.5 and later releases ( http://www-mipl.jpl.nasa.gov/install/sparcgraphics.html ). :-\

The demo (transparency_ovl) is working in general, but always if I want to take a screenshot the X Server will fail and terminate. Nevertheless there isn't much acceleration with my x86 box: no dedicated dev pipeline (dynamically-loadable shared object module) for the built-in graphics chip (CL GD-5428, 1MB DRAM).

Someone seen or know the following boards?
* DuPont Pixel Systems GLengine-24XP and GLengine-48XP SBus boards (2nd generation) for PX/ IRIS GL port for SPARC.

VME boards alternatives...
* Evans & Sutherland (E&S) Freedom Series 1000 and 3000 (stand-by graphics subsystem) using e.g. ES/PEX, XGL
* Vicom Visual Computing VX and MVX (1x/4x i860)

Soon try some of the XGL samples, running on my SS2 with GS graphics under Solaris 2.4.

BTW: PCD-4H using now a ATi Graphics Ultra Pro (Mach32) ISA board wit 2 MiB VRAM for higher resolution (1280*1024px @ 8bpp) in conjunction with 19" LCD for crispy clear fonts, ok better than before, because scaling could not be switched off with resolution less than the native one.

C compiler and XGL header files next.

After installation of all tools and utilities, including header files I managed to compile all XGL and XIL demos.
The output of the XGL demo "inq" wasn't what I expected: still many lines with "emulated in software"

Code: Select all

$ inq

My favorite demo "transparency_ovl" (transparency overlay) breaks in the moment the OpenLook window opens. With my x86 box there is no problem at all.

Code: Select all

$ transparency_ovl

XGL Version = XGL 3.1
Color mode = TrueColor
X Error of failed request:  BadMatch (invalid parameter attributes)
Major opcode of failed request:  138 (SUN_OVL)
Minor opcode of failed request:  4 ()
Serial number of failed request:  190
Current serial number in output stream:  196
Maybe some other application blocking or occupying the overlay map? - I have no idea.


Some of the demos are much faster, e.g. in rotation/transformation, compared to the x86 box w/o special XGL device pipeline but higher (internal 66MHz) clockrates. Also the sundiag test cases for the CG12 are much faster in displaying the results compared to the SPARCstation 1+ (Sun-4/65).

Hope to find better demos for the CG12, some day
