I don't know why I never realized this before, but
the Tektronix 4010
graphics terminal is implemented enitrely in SSI TTL logic and
contains no microprocessor. I guess that makes sense with it being
introduced in 1971, but it just suddenly hit me like a brick.
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 :-).
PS: anyone need a 4010 service manual online? I have
one and just
noticed it hasn't been scanned on the net anywhere.
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!
