ATI 3D Charger PCI add-on board (AF31552)
ATI 3D Charger, based on ATI ‘3D RAGE II +DVD’, 64-bit 3D graphics engine with 2 MB EDO RAM (40 ns), is
an PCI based graphics accelerator adapter (5 V, Bus Master device).
The amount of the EDO RAM can be upgraded up to 4 MB with an optional 2 MB EDO RAM memory expansion
modules (40 ns). The RAMDAC, which has 64-bit data path to the EDO RAM, can handle pixel frequencies up
to 170 MHz. The video interface is DDC1, DDC2B+ and VESA DPMS compatible. The adapter has an AMC
