The most certain and fastest way to open these locks is to drill a sight hole, determine and transfer a combination and then plug the hole. On the 8088's I have drilled the holes in different places and then swapped the back covers from one drilled lock to another. This way the drilled holes through the cover plate and the zamak body are no longer in the same place.
On those that you luckily got open, I hope you opened the change key hole door before relocking it. If the change key hole is open you can walk the wheels around with a sharp probe until they all line up and then set a new combination.
