Believe me, I hear you. I have a nostalgia for the 1970's and 1980's, but like you, I am beginning to toss in the 1990's and so on as well. I miss a lot of those sites too although I don't have time like I used to, haven't posted here as much in the last two years. The latter has been like a trip through Hell at times, I had my own "Twilight: 2013" when Mom got inflammatory breast cancer and passed away so I had to give up a lot and start all over. I did keep all my RPG stuff. IIRC, a good site is Paul Mulcahy's for lots of stuff. Another side I really miss and it has been quite a while was TR Walker's site, after he passed in 2006
it was gone. I have it archived somewhere.
