My favorite parts of the 4010 are not even SSI TTL. There's
a pot you turn up (I seem to recall a Unijunction oscillator)
and down to change the baud rate for example :-).

There was something pretty spastic related to Tektronix and
archives of their scope documentation a couple years back,
but what you need seems to be online at bitsavers.org right
now. You might have to look under "401x" instead of "4010".
Wow, 101 Mbytes for what I'm looking at right now!
