One thing to watch out for on the 5450A is burned out segments in the 14-segment LED displays. The display chip they used is rather weird (each 14 segment digit is actually two 7-segment displays mixed together) and VERY unobtainium. Mine has a missing segment on one of the digits and I have not found any replacements in 5+ years) The display is not critical to operation and my missing segment does not cause any digit ambiguities.

Seems like a work for a small cpld...
