Strange board from 02...

Unread postby konon007 » Sun Apr 30, 2006 5:17 am


Just pulled out the strange board form SGI O2 that I have got recently.
This is PCI board, but without any external or internal connectors.
On the board there are labels "Barco Graphics" and "COCOPCI-2.3".

Googling in Internet don't provide any info....

Any ideas?

Gonna guess it's part of a bigger Barco product, maybe a hardware colourspace conversion board or similar.

Found it mentioned in the O2 device driver developer tech pub. It was used as an example device driver. It's a Barco Chameleon used apparently for color correction.

The following quote is from comp.sys.sgi.marketplace:

I have got one in my Octane.
The PCI model works on O2 and Octane models.

It's a Chameleon Color Accelerator Card which is plugged into the
Silicon Graphics. The board speeds up the display of CMYK-data on the
monitor, color
corrections and color space conversions. So this speeds up generally

According to Barco:
"The Chameleon color accelerator is a plug-in board based on the
BARCO-patented Chameleon chip that speeds up color calculations on BG
workstations and proofers. Chameleon provides extremely fast and
accurate color representations of CMYK images on the RGB Reference
Calibrator, boosts the performance of Creator, and speeds up the
conversion of CMYK files to special ink separations
in the InkSwitch program. Chameleon is also used by several other
vendors in the graphic arts market to boost their color

They say it's less noticeable when working with fast cpu's, but it gave
my Octane MXE R12K 300 a very noticeable performance increase.

I bought mine from Ian. Very cheap, I know what they used to cost...

Hi Glenn,

Are you running a BarcoGraphics application like Creator? It only works
with this!

The driver is always installed during the installation of CTBrix based
applications, even if no Chameleon Color accelerator is present in the
When a Chameleon card is installed at a later date, no additional
installations will be required and the driver will be loaded

Ivo "

Hope that helps you.

Something interesting I came across while I was looking around the Developer's Toolbox:

It's the source code of a driver for that board. :)

Only if you have Barco products installed. It will display RGB-CMYK conversions faster to screen, and possibly aid in conversions. I have the Creator software, and remember there is a menu choice for it. However, it was originally designed for the Indigo 1 (way back in 1993!), so I don't know if there is any noticeable benefit using it on a more powerful O2 or Octane systems. There was also a Brush accelerator board, which seems a bit more interesting and even more rare. If you don't want to keep it, I might be interested to pick it up.
