Article-I.D.: sri-unix.4390 Posted: Thu Nov 25 05:38:41 1982 Received: Fri Nov 26 02:18:49 1982 From: Mark Weiser Date: 22 Nov 82 10:42:26 EST (Mon) Thanks to all who responded with useful suggestions. The problem turned out to have nothing to do with the LHDH itself at all, but was a bad DEC Unibus terminator board (bad capacitor). It was the suggestion to look closely at where the Unibus plugged into the LHDH which enabled us to spot a cracked capacitor. By the way, ACC seems to have fixed the problem with the shorted traces. There was no hint of that possibility on our boards.
