Yes, I found my way to this:
https://yamahamusicians.com/forum/viewtopic.php?f=56&t=4181
and their advice was to use the timing diagrams from the earlier HD63265 and make educated guesses for the rest of it.
Otherwise, more informative datasheet on HD63266 hasn't turned up yet.

Here's two pages I haven't seen before though (neat book! HD63265 two-page sheet is on the pages before):

https://electrelic.com/electrelic/node/689 has a little on what the differences between them are.

Duke typo'd, it's an H8/3003, not 3008. Same as the 3002 with 2 more DMA channels and 2 more external IRQs.

It hits what appears to be some sort of protection after that, but we'll see.

That's great, RB! While neither as interesting or versatile as PCs, those things were an important intermediate step for some people.
