Had an experience that gels with this. Advance of $1k per chapter (I wrote 3 chapters of an 8-10 chapter book) then without the publisher pushing it aggressively, royalties beyond that were minimal. The content did not date too badly so much as the presentation of it did.
Deadlines were brutal, especially incorporating edits and requests to expand/etc. That was a brain-melting experience. Sourcing and providing screenshots was particularly annoying.
Be prepared for it to be tougher than you expect and (as Patrick said) not to earn anything after the advance. Just when you feel like you're done, they'll come back with edits that double your workload.
Before long in my writing experience, I had "THINK ABOUT THE MONEY" taped to the top of my monitor. It was the only way I got through it. Interesting to do it once, but I'm not sure that I'd do it again for a publisher.
