You can find some old ones, on archive, if you search for some sites they've posted the podcast on, in the past. I think I was able to find back to 165 or 175? Out of the 4-5 sites the podcast has been posted on, I think only one or two of them had an archive that far back, that I could actually download the mp3 from. If I remember correctly, I had to inspect the page, find the mp3 URL, and download it that way.
