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!

To get the best possible experience you will need a robust newsreader (client software, e.g. Thunderbird) and then some Usenet provider (e.g. Kevin Bowling's CSIPH server or Eternal September).

If you are just stopping by or have trouble setting up the reader, the "ready to use" but fairly limited Google Groups web interface may be a better option for you.

We are looking forward to seeing you there!
