Oberon (moon) geological feature on Oberon: craters and chasmata ('canyons'—deep, elongated, steep-sided depressions which would probably be described as rift valleys or escarpments if on Earth). Oberon's surface is the most heavily cratered of all the Uranian moons, with a crater density approaching saturation—when the formation of new craters is balanced by destruction of old ones. This high number of craters indicates that Oberon has the most ancient surface among Uranus's moons. The crater diameters range up to 206 kilometers for the largest known crater, Hamlet. Many large craters are surrounded by bright impact ejecta (rays) consisting of relatively fresh ice. The
Oberon (operating system) and Paul Reed completed a re-implementation of the original Oberon System for the Digilent Xilinx Spartan 3 FPGA Starter Board. The work included a revision of "Project Oberon", identified as Project Oberon (New Edition 2013). The system has since been ported to a Xilinx Spartan 6 FPGA Development Board by Saanlima Electronics. In 2015 Paul Reed collaborated with Victor Yurkovsky in the creation of OberonStation, a Xilinx Spartan 3-based computer designed specifically to run Oberon.
