I know about Chris Espinosa (https://en.wikipedia.org/wiki/Chris_Espinosa). I didn't think anyone else had been their 30+ years.
To be a single-digit employee, you had to start in the 70s -- i.e., 40 years ago. My friend -- I don't think it'd be appropriate to name him -- has "only" been there 30, which means he joined a healthy-sized Apple already 10 years into its life.
In 1994. Apple was on top of the world. They were the number one or number two computer seller and the PPC Macs were introduce and then Windows 95 happened.
