You're lucky. Really lucky. I spent over a decade trying to get one of those machines and only recently settled on a $650 AltairClone as the original machines are now fetching over $2000. It will need a number of modifications before it will be ready to accept an S100 backplane.
Also, Cromeco Dazzler's aren't that complex. I'm sure if you can come across someone willing to make some really high quality scans or photographs you can probably make new boards and order in the necessary chips. It's all 7400 logic. I'd be in for a set of empty boards if that idea ever floats.
Edited: It looks like all the information you require is in the "Cromeco Dazzler Schematic and Foil Diagrams", which I have yet to find in PDF format, but there's also a decent amount of information in the manual which will go a long way towards manufacturing new boards.
