...would be to build a hyperlinked collection of photos of the C2/R2 which then drill down to the collection of sourced parts we've found as replacements. So, there's an HTML page with an image of the C2 on it. Using a client-side IMAGEMAP, there are regions which correspond to the subassemblies and then further, into the parts themselves. You'd have links to the places where you've found a perfect match. I'm here on the digi-key page for two-pin JST connectors, for example. I've just done the work necessary to determine that this is the right part but a lot of other printer owners have to re-invent that wheel and re-do the effort if they want one.
