They don't look too bad. Do you see any small roots growing? They would be white with green tips hiding at the very base of the pseudo bulb?
Have you ever grown a pineapple from the leaves on the top of the pineapple? Maybe in grade school? Well I ask because oncidium type orchids have a type of cell that grows roots at the base of the bulb. Even if the roots now in the potting mix may be rotten (if they are) you can still get roots to grow. Can you get any sea kelp liquid for plants? That has a hormone in it that is very good for encouraging root growth. Before saving it, seeing flowers or anything, you need to stabalize the plant and get it going. Oncidiums have very fine roots as far as orchids go. They rot easily. The good news is they also grow fairly easily, and now, in the Northern hemisphere is their growing season. Since they have small roots they take a smaller gauge potting material, but well draining. They also want to consume a lot of water to fill their bulbs. They also need stronger light than phals.
