I loved using the manuel method!  I even went so far as to derive the orbit equations myself.  But it was exciting when the tracking software for the Timex Z-81.  Still have have one in the shack.

Hi Smith, N4VIL

Early in 1972 I was receiving by regular post the 2 Line Orbital Data from
Goddard to be used for the meteorological satellites ESSA-8, NIMBUS and
TIROS

For traching I used as well the azimuthal map of the earth with a foot print
transparent overly and a revolving satellite orbital path.

Yes...no computers at all in the Ham shack at that time but manual tracking
 using a map a pencil and a clock was a beginning very useful and exciting.
