A couple of thoughts on this:
1. You can look on the internet for another Qlink Processor and get a IP enabler so that anyone will be able to remotely program and back up the system.
The Qlink Processor is way beyond end-of-life and cannot be repaired by Vantage.
The Power supply is the weak link, so you can scrap one out of another processor to keep things going.
2. You can purchase an Infusion Processor and backplane board that fits your cabinet and join the network. Now things are easily diagnosed and setup locally or remotely.
The Infusion processor is a native ethernet device.
It also has an SD card for backup that can be copied and kept in a safe place.
The processor will work the old modules, but not all of the old LCD touchscreens.

There may be more damage to the system from the storm than just the Processor. You may also have module (s) that are damaged and wiring.
