I recently received these diagrams of the Headquarters Support Activity's east and west compounds from Les Duffin. (Thanks again, Les!) Click on either of the images to see a larger version.
The east compound was where the US Taiwan Defense Command was located, as well as the Navy Exchange, commissary, theater, library, beverage store, snack bar and several other offices and services.
I attempted to overlay the Google Earth view of the east compound area with the diagram, but I can't decide whether or not I have the correct scale. In any case, I think it provides a rough approximation of the area as it existed during the 1970s. Please post your comments if your memory is better than mine on this.
Here's the diagram of the west compound, which was located to the east of where the stadium is located today. The bowling alley was there, as was the chapel, Pass and Registration and the auto repair shop.
