As I understand it, cctech is just a duplicate list of cctalk, but moderators filter out anything considered off-topic for the cctech users, so they *only* get to see messages related to vintage systems. You don't need to be subscribed to both lists - pick one or the other depending on whether you like the occasional* off-topic traffic or not. * it varies, sometimes there's a lot of off-topic content on cctalk compared to posts about vintage machines, but at other times hardly any. Lots of us who are signed up to cctalk have common interests broadly based around science and engineering anyway, so we find even the "off-topic" stuff interesting. cheers Jules
