So, if bugs didn't exist, it'd just be members of the Operation enum to go.

Starts a dash towards just completing the addressing modes for now.

Accepts that whether instructions do 8- or 16-bit bus accesses depends on either M or X depending on the operation.

Many of the rest cover only one or two opcodes so this puts me at 216/256 opcodes covered; 35/47 bus programs; just more than 5/7 pages.

That's: 122/256 opcodes; 22/47 bus programs, ~3.5/7 pages transcribed. Maybe I'll be able to get to the runtime stuff sooner rather than later?
