I enjoy playing around it with it for the programming challenge of targeting such a constrained platform (a 4MHz Z80 with 64KB of RAM for my system). It's simple enough that you can hold the whole system in your head when you're working on it. Basically the same things I do with embedded platforms like Arduinos, except my old Z80 system can host its own Turbo Pascal compiler.
