Jeffrey Gao Hexadecimal System
From OCE Space Simulation

The Jeffrey Gao Decimal System data reference sheet in Copernicus in May 2006.
The system was etched in permanent marker on the Keplernicus cork board. After the room change of 2008-09, although many items still carry labels, the JGHS has yet to be re-implemented, perhaps due to ambiguities in Quartermaster role.
