Nostalgia for Retro Computing

Happened upon some G+ content on the wayback machine today:

Just 20 posts visible in this snapshot - infinitely scrolling feeds not playing well with the internet archive.



Is there no replacement for the lost web sites? The wayback machine
is good for achived stuff, but not for stuff that could be updated?
Are there any good sites for the uncommon non byte sized computers,
Molecular 18 comes to mind with a 17 bit ALU.
