The CSIPH Newsgroup
comp.sys.ibm.ps2.hardware
aka "CSIPH" is a Usenet newsgroup dedicated to PS/2 systems, even the non-MCA ones.
It is inhabited mainly by people who are enthusiasts, obsessives, M.A.D. or all three!
If you are just stopping by, the easy to use but somewhat limited
Google Groups
web interface is probably the best option for you.
However, for the best experience, you will need some kind of newsreader
(client software, e.g. Thunderbird)
and then some Usenet provider (e.g. Kevin Bowling's CSIPH server
or Eternal September).
We are looking forward to seeing you there!
