Takahashi has a neat pole finder built into the
RA axle of some of their mounts - IIRC you set the
date & local time dials, rotated the pole finder to where
it shows level on a bubble, the reticle then shows an elongated box 
for where to put Polaris. The box was marked for location
as a function of precession 1950 - 2000. NO computer
display required.
