The yellow alligators reconnect Paula's INT6 to Even CIA.
The trace was badly corroded around U190, the Ricoh realtime clock, and my clumsy attempts to clear those pads finally killed INT6 for good, causing AmigaOS to hang at boot 😢
Since I couldn't find a suitable pad beyond the Varta blast area, I'll re-route INT6 all the way across the motherboard to CIA.
