Retro networking / WAN communities

[Grant Taylor]

Hi,

Does anyone know of any communities / mailing lists / newsgroups / et 
al. for retro networking / WAN technologies?

I find myself interested in (at least) the following and would like to 
find others with similar (dis)interests to chat about things.

  - 10Base5 / 10Base2 / 10BaseT
  - ISDN
  - DSL / ADSL / SDSL / HDSL
  - T1 / E1
  - ATM
  - Frame Relay
  - ARCnet
  - PSTN / PBX / PABX
