There's rumors of a TTL prototype board out there, but if not, a chip may
well need to be depackaged/deprocessed and probed manually to figure how
just how the heck the thing works.
To my knowledge, there's no surviving VHDL or somesuch to actually tell us
how the durned thing works - it's a little black box.
