I had some fun looking through the Internet Archive, just out of curiosity, and I’m sure I’m not digging up anything people don’t already know. The good news is that a lot of snapshots of the twit.tv web site have been captured all the way from May 3, 2005, and they make fascinating reading.
What’s interesting is that the last snapshot taken in 2009 was on Nov 17, and there’s no sign of Maxwell’s House as a TWiT show on that date. The next snapshot is for Jan 5, 2010 (and the home page contains some interesting musings from Leo on the subject of funding the network). Maxwell’s House now appears in the list of shows, and the link goes to a twit.tv page archived on Dec 28, 2009 for MH 52, which shows MH episodes back to 50, exactly the same as the episodes held on the current site. That makes it look like the first 49 episodes of MH were not classed as a TWiT show, which is confirmed by the TWiT wiki which says that it became an official TWiT show in Dec 2009 http://wiki.twit.tv/wiki/Maxwell's_House .
There are show notes from ep1 onwards on the TWiT wiki, starting at http://wiki.twit.tv/wiki/Maxwell's_House_1
Each episode gives a location for a file page on odtv.me - this server seems to have disappeared but the pages have been archived by the Internet Archive, however the actual mp4 files were held on a server called kiwinerd.ca and the couple of files that I checked had not been archived by the Wayback machine.
I also found that mp3 files of episodes 2-30 had been held on open.ashannon.us (another dead server). The Wayback machine successfully archived the index page in 2009 at https://web.archive.org/web/20090629142103/http://open.ashannon.us:80/music/Maxwells-House/
but it seems that none of the mp3 files linked on that page have been archived. Putting the mp3 file names into Google drew a blank as well.
So sadly it does look like they’ve gone, unless someone has their own offline archive.
You can tell I’ve got time on my hands right this moment…
