Default Legacy OpAmps

I purchased a beautiful Digital Equipment "Power Supply Noise Amplifier" -- talk about legacy devices -- there is a Burr-Brown OPA600CM and a National LH4004CD -- I know that the latter will drive a 50 ohm load for a spec analyzer and I believe that the BB unit is an early dif or instrumentation amp. Anyone have a clue about these devices?
