  There is an abundance of equations of Painlev\'e type besides the classical
Painlev\'e equations. Classifications have been computed by the Japanese
school. Here we consider Painlev\'e type equations induced by isomonodromic
families of linear ODE's having at most $z=0$ and $z=\infty$ as singularities.
Requiring that the formal data at the singularities produce isomonodromic
families parametrized by a single variable $t$ leads to a small list of
hierarchies of cases. The study of these cases involves Stokes matrices and
moduli for linear ODE's on the projective line.
  Case studies reveal interesting families of linear ODE's and Painlev\'e type
equations. However, rather often the complexity (especially of the Lax pair) is
too high for either the computations or for the output. Apart from classical
Painlev\'e equations one rediscovers work of M.~Mazzocco, M.~Noumi and
Y.~Yamada. A hierarchy, probably new, related to the classical $P_3(D_8)$, is
discovered. Finally, an amusing ``companion'' of $P_1$ is presented.
