Workstation 4 System Block Diagrams

In the following pages, the three major configurations of the original Workstation 4
are presented. Each highlights the system board and LCD configuration as it changes
over time. Figure 2-1 shows the initial configuration of the WS4 with System Board
AB28-F/G and a Samsung LCD panel.

Functionally, there is very little difference between AB28-F and AB28-G. The
majority of changes were implemented to improve EMI emissions, and lower
manufacturing costs.
The illustration also shows the Samsung LCD panel and companion LVDS Receiver
Board, designated XB34.
This configuration was produced up to August 2004.
