The 737-200 that crashed was a 40-year-old airframe, and the crash characteristics are only similar in that they all occurred shortly after takeoff. The 737-MAX-8 crashes occurred within 6 months of each other, both on a brand new airframe on a new aircraft with a new control and sensor system that produced VERY similar profiles in rapid climbs and descents that point to an issue with said new autopilot. The MAX-8 and the 200 are VERY different aircraft, even if they're fundamentally built around an original ancestor.
