Does there exist an archive somewhere of posts to the USENET newsgroup sci.math.research?

The best approximation I'm aware of is Google Groups. However, despite the Google brand name, the search capability of Google Groups is abysmal, and it is hard to tell how much content is really archived there.

I have an old bookmark to a Math Forum URL that currently seems to be dead. An old website called the The Mathematical Atlas indicates that the Math Forum moved to forum.swarthmore.edu but that site currently seems not to be working either.

The Usenet Archives website, as of this writing, seems to have archived a grand total of two (2) posts from sci.math.research. EDIT August 2022: The Usenet Archives has now archived much more of the content, but there is no easy way to search it.

This question was prompted in part by another MO question, Looking for source: “How not to be a graduate student”, which hints that the desired transcript may have been posted to a USENET newsgroup such as sci.math.research or sci.math. In my opinion there was some valuable content posted to sci.math.research and it would be a shame if it were lost forever.
