This time didn't need any help as the previous chapters (and cadet's

generous help spurring me to understanding) prepared me for the concepts involved, and most of the chips were mainly reimplementation. I did go through some trial and error on the PC chip.
About that PC chip: my register always has a true load flag. What are the ways around needing a true flag, if any?
I would appreciate seeing alternate working implementations of the PC chip, so please send them in e-mails. Cheers!
