It's cute, but only marginally useful IMHO.  The hardest part about learning ASM coding is understanding the interaction of the registers and flags.  It really requires a stepwise debugger to see what is going on, understand how branching is occurring and so on.  Without the ability to step a running program, it's only marginally useful since you have to guess-and-check.

I like that it has a small graphics mode built in though, that can be useful.

That being said, I've seen some other cool ASM tools to add to the list.
