It should be possible to run CAM on a system of that vintage provided you perform a little porting effort. I'd have to go look at the CVS logs to determine just what you would have to bring into your system in order to run CAM. >Am I asking for major trouble if I up-rev to a recent (like last night) >-CURRENT? I can't say. I don't believe that CAM will contribute to any instability though. >-- >Karl Denninger (karl@MCS.Net)| MCSNet - Serving Chicagoland and Wisconsin >http://www.mcs.net/ | T1's from $600 monthly to FULL DS-3 Service > | NEW!
