Discontinued: 30/11/1999.
The PCI GXT255P Graphics Adapter is a more powerful board for Escala S Series.
The GXT255P provides excellent 2D 8-bit, 16-bit, or 24-bit graphics performance for Escala S Series.
It is designed for 2D applications including desktop publishing, X-window applications, 2D
mechanical drafting, CASE, chemical and biological applications, and electrical CAD.
The GXT255P has 8-bit, 16-bit and 24-bit true color depth and allows simultaneous display of the
entire palette of approximately 16.7 million colors.
These accelerators may also offer an exciting level of soft 3D performance. Its 8MB of VRAM (6MB
frame buffer plus 2MB auxiliary buffer) provides outstanding support for high-end graphics
applications.
