Increasing the Video Memory
Your computer comes with at least 512KB of video memory.
You can increase the video memory to 1MB by installing four
256K x 4-bit DRAM, 20-pin, ZIP (Zig-zag Inline Package) chips.
This is useful for running graphics-intensive applications or for
supporting resolutions up to 1024 x 768 or more on your
monitor.
The following table lists the video DRAM ZIP chips that you
can install on the main system board.

shown on page 4-3. The chip sockets you’ll use are the
empty ones, numbered VMOO through VM03.
