It's obviously correct to say that the 68EC020 has a 24 bit address bus and not a 32 bit one. However, that doesn't make it a "crippled, mangled" version though. Cost reduced, yes. But crippled and mangled makes it sound like a bad CPU and that's not a fair assessment IMHO, a 24 bit address bus allows for 16MB.

Remember that in 1992, 16MB of RAM was still a huge amount. Many PC motherboards only supported about that much and almost no one actually had that much memory in the consumer or even business space. Only highly specialized professional use required that much (or more). It wasn't until around 1995/1996 that system requirements started creeping up towards 16MB required (Windows 95 for instance recommends 8MB of RAM be available, Windows 98 requires 16MB).
