Virindi OCS
From VirindiPlugins
VirindiOCS (Old Comp System) is a plugin that tracks the burning of components, predicts runtime, and allows you to purchase the proper ratios of components for a particular approximate runtime. The goal is to make it easier for you to use old components (with peas).
If you haven't tried old components lately, in certain circumstances, they allow you to run for much longer without recomping.
VirindiOCS is not part of the Virindi Bundle, but it does display with Virindi Views if you have VVS running. It is also designed to play nice with other Bundle components, including Virindi Chat System 5 and Virindi HUDs (it provides statistics to the new Status HUD when available).
