Author here for all your questions about vintage standard-cell logic :-)

Ken, you have done an amazing job with this writeup. Very clear and understandable.

I recommend this article for anyone wants to understand how Integrated Circuits operate and are built.

BTW, I worked as the Cost Engineer for the IBM Token Ring cards and also the RS/6000 Memory upgrade boards as an intern in the early 90's.

I don't have anything to add to the discussion but I really enjoyed your article.
