Marks Rpi Cluster continues to run 24/7. We're currently running Einstein BRP4 work on all the nodes and when it has work fetch issues will run the occasional Asteroids@home work unit. Most of the nodes have a recent average of 1100 credits with ten of them pushing 1200, so they are doing as well as they can.
I've heard nothing further from BitScope regarding getting an updated EC12 (Edge Cluster 12) so I am not sure what is happening with them. Ideally I would have liked to upgrade the cluster to Pi5's but that doesn't look like its going to happen.
