Can I somehow access the contents of the old website (ompf) ?
There are a few scattered records available on the Wayback Machine, though most forum posts did not make it. I think that's all that's left publicly available, the Google caches have long expired. IIRC there have been efforts to try to recover as much as the site as possible, but not much at all was left... take a look for yourself:
For some reason the board was only archived sporadically, it seems the forum software wasn't really compatible with the archival web crawler.. case in point towards the importance of reliable personal archives, I suppose.. Maybe ask around?
