Chapter 5 - Programming the VMEbus Interface.

  PMC-1 Video Module

The EPC-9 uses the PMC-1 Video Module for SVGA support. The PMC-1 uses a
Cirrus Logic CL-GD5446. The video module connects to the PCIbus and has 2MB of
VGA memory, and resolutions from 640 x 480 (256 colors) to 1280 x 1024 (256
colors). The PMC-1 is described in full detail in Appendix G - SVGA and the PMC-1
Video Module.
