Now, first of all, to be honest, I don't know if Welles appeared in all of the episodes or just some. He is in the compilation, but that's the only episode that is available.
For some time, Network was planning a DVD of the whole series:

But it was delayed and now appears to have been cancelled, it's no longer on their website.
I have reason to believe a few episodes have been around on VHS, so I thought I'd try my luck.
