Random Continuous Play on Rock-Ola 469?

Without having any documentation on hand for this machine, I'm
wondering if there is any way to get this playing continuously with
random selection. Either with a factory setting or modification done
in the basement? I just finished cleaning and repairing the 469 that I
picked up on the side of the road earlier this summer and am anxious to
see if I can get it functioning in this way.

Not random selections.You can disconnect the read out arm cols and it
will not cancel selections made, but it will just play those songs over
and over. If you want a service manual. please contact me.
