The nice thing about assembly is that once you know one, others are
easy to learn to permit you to write code that you can test. You can
have a look at MIPS for delayed slots, SPARC for register banks, ARM
for instructions that do multiple operations at once and you'll have
seen most of the basics that you'll ever need. Also all of these are
RISC based and cannot load a full-length register in a single instruction,
that's possibly the most confusing thing when you come from x86. And
it's also very interesting to see differences in constraints ;-)
