hOp – a microkernel OS based on the Run Time System (RTS) of GHC, an Haskell implementation.

By removing the system-specific bits, and just adding a few lines of C and assembly code, it turns into a standalone micro-kernel that can be extended in Haskell language.

All functions from the base hierarchical library outside of the System module is available. This includes threads and communication primitives and the foreign interface, which means experimenting with writing drivers in Haskell should be reasonably easy.

The hOp operating system was under development ot the School of Mathematical and Computer Sciences, Heriot Watt University, UK.
