[dm-l] Early Digital Editions

I'm sure this has come up before, but as part of something I'm working on, I've come across a whole trove of early (i.e. mid-1990s) on-line editions. In this case often designed as class projects and entirely non-medieval.

This makes me wonder if there is a "hidden corpus" of medieval digital editions out there--either still available on some murky corner of the web or lost due to restructuring of URLs at host institutions.

I wonder if it would be interesting to collect as big a bibliography of these as we could. If it turned out that there were hundreds, I'm sure I could whip together a web-form to allow bibliographic entry. But to start, what do people know of?
