I assumed from the date that it was servos. They didn't start using steppers
until much later. I'm pretty sure this thing is REAL OLD. I seriously doubt
it was from the '70s, with that thumbwheel manual input. You certainly would
go crazy trying to do anything manual with that.

Also, there seem to be a lot of cables hanging out of the axis drive boxes.
That also suggests servo. There may be somthing missing from the axis
drives, as there are round areas missing the paint, with a 6 bolt hole
pattern on them. I suppose that could be an access port, or a window
for viewing something.
