[[Howard Vollum]] himself wrote the introduction message on page 1 of this supplement, where he presented the 7000 series as a replacement to the [[500-series_scopes|500 scope series]], emphasizing the necessity to switch to a new platform for modular high-end scopes due to the limitations of the original [[500-series_scopes|500 series platform]] designed in 1953.

According to Vollum, a significant portion of the previous two years' $28 million engineering budget (~250m in 2023 dollars!) were spent to develop the initial components and products of the 7000 series.

The initial family [[introduced in 1969|introduction in 1969]] consisted of the 90 MHz [[7504]] and 150 MHz [[7704]] mainframes, and no less than 13 plug-ins − the [[7A11]] FET-probe amplifier, [[7A12]] dual-channel amplifier, [[7A13]] differential comparator, [[7A14]] current-probe amplifier, [[7A16]] singles-channel amplifier, [[7A22]] differential amplifier, [[7B51]] and [[7B70]] delaying timebases, [[7B50]] and [[7B70]] delayed timebases, [[7S11]]/[[7T11]] sampling system, and the [[7M11]] delay line.

While the original [[7504]] and [[7704]] mainframes were short-lived, the series lasted until the early 1990s, with some of the original plug-ins like the [[7A22]] or the [[7S11]] remaining in production throughout.
