Alex Forencich has been live streaming rebuilding Corundum starting a few weeks ago: https://www.youtube.com/@AlexForencich/streams

As I understand it Taxi is where new development is happening: https://github.com/fpganinja/taxi

This is correct, and the result of those streams has been released as corundum-proto here: https://github.com/fpganinja/taxi/tree/master/src/cndm_proto . Note that this simplified design is intended for educational purposes only, the "production" variants will be much more capable (corundum-micro, corundum-lite, and corundum-ng).
