The companion delaying timebase for use in 4-slot mainframes is the [[7B85]]. The [[7B50A]] is essentially a 7B80 with its fastest calibrated sweep rate limited to 5 ns/div. | The companion delaying timebase for use in 4-slot mainframes is the [[7B85]].

[[Les Larson]] developed the trigger circuitry and served as Project Manager for the 7B80 and 7B85. | |||
The sweeps were designed by [[Bruce Hofer]] and the DVM and related logic by [[Paul Farley]]. Much credit is due [[Art Metz]] for his work on the trigger input 1C which includes the peak-to-peak automatic trigger circuitry. | |||
[[Gene Andrews]], Program Manager, provided overall direction for the project. | |||
