In what? In video games? the 6100 _might_ have been
a competetive
architecture when it was new in the mid-to-late 1970s, but as
competition against an early 8-bit micro, not a 16-bit micro, which
the T-11 is.
There is a PDP-8 processor used in Atari's Escape From the Planet of
the Robot Monsters. Look for it.
