Ask HN: Sources of historical HN-type discussion during past tech bubbles?

I am interested in reading raw, unedited "intelligent" tech discussion similar to HN during past events such as the dot-com bubble, for personal interest and education. I want to get an idea of the genuine state of discussion during these events without any kind of hindsight bias - what predictions were being made, how were people justifying valuations, were people warning about overvaluation, etc. What interesting sources are there for this?
