We have an archive of the first 100-ish Upstairs and MM threads, along with a few miscellaneous threads.
https://miku.neocities.org/
Take in mind they are compressed archive files with all their files, so you'll have to download them if you want to read through them. They also link to 8ch for resources, so they won't load correctly without editing the .html files manually.
The rest is still unarchived though, and 8archive stopped working a long time ago.
