These discs were sent to me by, as you've probably guessed; BetaCollector (ReflectiaX). So a huge thanks to him as always for making this possible. I am also aware that anonimas uploaded some Japanese versions of this build on Internet Archive a while back - including that same Advanced Server build, although the other two discs that he uploaded are in the DEC Alpha architecture. I've also provided pictures of the discs for this thread, along with screenshots of the actual Japanese builds themselves. You can also download ISO images of them here: https://archive.org/details/w2ki-jpn
Have fun!
