I’ve been digging around for info on what the option board is actually for and how it’s to be installed/used. Is that documented anywhere?

Bit late - but it converts the pinout of the NABU expansion slots from a cable from the motherboard to each card, to a daisy-chain starting at the motherboard and going to each card in turn.

It reduces the total length of the expansion cables and in turn the capacitive and inductive load they put on the system bus.
