@Ellico2020bis The 555 timer IC had 8.
@sirgeefive Also, if they were memory, they were probably 18-pin, they needed parity, they were so unreliable.
@sirgeefive I built an audio oscillator circuit for an alarm based on a 555 timer when I was in 9th grade. Was a cool project. @Ellico2020bis
@sirgeefive I know of plenty that had fewer than 16, but, figured 16, especially socketed, was a large enough contrast versus the 2020's.
