From the project
Stuff to put a FPGA in a SBus system (SPARCstation)
The goal of this repository is to be able to interface a modern (2020 era) FPGA with a SBus host. SBus was widely used in SPARCstation and compatibles system in the first half of the 90s. It was progressively displaced by PCI from the mid-90s onward, and is thoroughly obsolete.
So unless you're a retrocomputing enthusiast with such a machine, this is useless. To be honest, even if you are such an enthusiast, it's probably not that useful...
