Also, the monitor on pre-][+ machines with integer BASIC also had a mini-assembler, so short assembly programs could be typed in as such instead of keying in the bytes. Both versions of the monitor had a mini-disassembler. On the other hand, I still remember at least a few 6502 hex opcodes, not that I have any use for that information anymore. The instruction set is small enough that it doesn't surprise me that Woz would have it memorized.
