"Overboard" comic archive?

Overboard (comic strip) - Wikipedia by Chip Dunham is a daily strip chronicling the misadventures of the hilariously incompetent crew of the anachronistic pirate ship Revenge. It’s main publisher Go Comics has an archive, but the strip begin in 1990 while the archive only becomes complete from early 1996. I was looking for a particular strip that doesn’t seem to be there. Are there any sources for the earlier strips?

There are a number of online aggregators, but even if the strip was published openly, I’m not sure of the legality of the various sites. I believe the author does publish / did publish some collections, which is probably the best option for a legally safe review of work that may no longer be available online.
