From that vintage, it is most likely DC brush motors with DC tachs,
and from the label, it sounds like 2500 cycle/rev shaft encoders.
With sufficient searching on the web, you might be able to come up
with pinouts for the connectors, voltages, etc. Don't assume the encoders
are +5 V and TTL output. They could very well be 15 V input and
analog or 15 V open-collector output. These can still be connected to
modern encoder counters with minimal circuitry.

If the servo drives still are in working condition (and are of a performance
level that is still useful) then you could save some trouble by using them.
If not, Copley Controls makes some relatively inexpensive servo amps that
should drive the motors.
