It's basically machine language (i.e. lower level than assembler). I remember programming in machine language on an Apple II - I had no assembler, just a photocopied table of the OP codes, and I calculated them myself and entered the hex numbers and ran it.
I wrote part of a tetris clone that way (although never finished it).
Exactly. My very first thought was why on Earth would you even bother trying to program using that? Write an assembler, and then write a C compiler, for goodness sake!
