In your bottom picture, do you see in the bottom left, there is an area outlined with a dotted line?
That was the Honda development area and what Hondata and "chips" use to reprogram the ECU. So that's where the new components will be soldered in.
So, ya, without going over it with a fine tooth comb, it looks like a complete stock ECU with no issues.
Huh. Why did I think it was the P72 you wanted to aim for if you were going to chip your ECU? It's been a looooong while since I've tinkered with my DC2.
