Matrix C-32 card
RAM upgrade to 1MB
 

MATRIX C-32 Graphic card
Video memory upgrade to 1MB

     The Board is used to upgrade an original 256kB Video RAM Board on a Matrix C-32
MegaST Bus graphics card to 1MB Video RAM. Simply unplug the old 256kB Video
RAM Board, remove the small white DIL resistor network, and plug in the new 1MB
Board in. The Matrix VMG automatically detects the 1MB Video RAM.

     The Board files were created with Eagle 7, and the Gerber files were produced once
via JLCPCB, the PCB built twice, and successfully tested. It is a 4-layer layout.
