The AGX015 from IIT was a the successor to their earlier AGX014 graphics accelerator. It could be used on both ISA and VLB cards, could support up to 6 MB of VRAM video memory and provided 24-bit colour depths at a resolution of 800 x 600 or a maximum resolution of 1600 x 1200 at lower colour depths. The AGX015 was also used on the Hercules Graphite VL Pro and Spider Black Widow VLB. It included a number of graphics acceleration features including BitBlts, line draws, complex polygon fills, circles, ellipses, and surface mapping and shading. Its memory was clocked at 65 MHz.

Supports up to 90 Hz flicker-free refresh rates, 16.7 million colours, and resolutions up to 1280 x 1024 (in 16 colours non-interlaced).

The Celcius was never released as an ISA card.

 

Board Revisions

I have no information on the various board revisions for the Celcius VLB, with only rev.1/B2 known.

 

Competition

In 1993, the Orchid Celcius/VLB competed directly with other mid-range to high-end cards including the Matrox MGA Ultima, Hercules Graphite VL Pro, and Number Nine GXE.

 

In the Media

 

"Orchid Technology is shipping a new VESA local-bus Windows accelerator and a 16-bit digital signal processor (DSP) sound card. The Celsius/VLB, which has 1MB of video RAM, supports color dithering, polygon fill with reference pattern, polygon window mask, and image stretching and scaling. It can be upgraded to 2 MB of VRAM for 256 colors at 1,280-by-1,024 noninterlaced. It provides 16.8 million colors and a 90-Hz refresh rate."
