I just wanted to say thank you for all of these write-ups, and for the restoration and reverse engineering work that you do for the retrocomputing community.

Here's a question: how has this implementation changed in modern nano-scale ethernet implementations? Modern ethernet cards are asked to do much more offloading and processing, potentially including application protocols like TLS and DMA not just from memory but directly from NVMe devices as well. Given that we can now spam out transistors by the billions, are things like 10-bit counters still implemented via clever dynamic logic in hardware, or is there a more brute-force approach in use today?
