The other big notable thing for assembly is that it isn't portable. Assembly is very different for every processor architecture, unlike something like C where you may have to make some adjustments between an x86 vs ARM proc, in assembly you're basically rewriting it from scratch

Also, this is an obscure assembly variant specifically for the computers in the Apollo mission. Not sure about the specifications on that, maybe there is a handbook, but I doubt it.

Rewriting the code to x86 or anything seems improbable since you'd pretty much have to guess what the instructions are actually doing.
