Adds two-thirds of absolute long.
...
Working total: 31 opcodes covered; 10/47ths of bus patterns.
Next is JSL, which I think will require additional operations.

Adds enough logic to start serialising instructions to somewhere.

Completes absolute indexed indirect micro-ops.
...
For the record: this is just six out of forty-seven codes complete. Or about two-thirds of six pages. Plenty to do even before I start trying to interpret these things.

Immediately runs afoul of a read/write difference in the specs between 8/16-bit mode that suggests maybe this isn't a good structure.
...
Perhaps generators of some sort?
