I did miss that, true; however, Assembly is heavily architecture-tied. Therefore x86 Assembly significantly differs from, for example, ARM assembly, but nonetheless I should have mentioned it.

Its annoyingly incompatible and RISC is more verbose but really the concepts are pretty much the same. Load something to a register, do some very basic operations on said registers and save it out. An X86 programmer should be able to pick up other CPUs fairly easily. Although delay slots will probably piss them off every time.
