Any idea/recollection of why the 316 TIP hardware was ditched and replaced
with the C/30 for the TAC? Just to have more modern/maintainable hardware? (I
recall the 316 was made of a lot of tiny cards.)

I definitely read a document about the MBB. I have this vague memory that it was
hardcopy, but I doubt I'll be able to locate it anytime soon.

ISTR that the MBB took a daughtercard, which implemented extra functionality,
and the C/70 took its own; I don't recall exactly what the C/70 one did,
