J.HILL's posting implies that there was something that looked like a broken-off pin in the corresponding hole in the socket. If that's the case, then his deduction was very reasonable. I have recently dealt with cables where the socket slot corresponding to the missing (keying) pin was filled with plastic. No problem, no panic. It seems to me that whoever made this connection brought this on themselves. Jacob Gore gore@EECS.NWU.Edu Northwestern Univ., EECS Dept. {gargoyle,ihnp4,chinet}!nucsrl!gore
