Some years ago, I asked a engineer friend about the ceramic terminal = strips (and accompanying spool of silver solder) that I had seen in Tektronix = scopes. He responded by asking me what a terminal strip was supposed to do. Erm, make connections and provide physical stability between some wires = while keeping all the connections insulated from each other? He said "yup", = that's what these strips do. In particular, they aren't capacitors, resistors, = or inductors to any significant degree... On a vaguely related note, I found it amusing that there was a well = known hack for Cray's (or perhaps 6600's) which were misbehaving: put a Tektronix = scope probe on a test point that generally had one there during final system = checkout. The load (extremely mnimal by design) was just enough to stabilize the = system. -r
