Professional Graphics Controller: Specifications, Development & Hardware derivatives
Professional Graphics Controller (PGC, often called Professional Graphics Adapter and sometimes Professional Graphics Array) is a graphics card manufactured by IBM for PCs. It consists of three interconnected PCBs, and contains its own processor and memory. The PGC was, at the time of its release, the most advanced graphics card for the IBM XT and aimed…

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Professional Graphics Controller, one of the stronger structural bridges in this analysis connects Professional Graphics Controller with Specifications. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
