Sought to simplify the way partial machine cycles are communicated, for ease of machine implementation. Also implemented the wait line.

Started trying to wade back to passing tests. Working on the new timing tests first, and focussing on getting the Objective-C test machine to compile bus operations into machine cycles, which means indicating phase to all-RAM delegates.

Ensured that -description can handle the newly-captured bus actions.

Continued filling in tests, fleshing out what the test machine captures as a result.

Implemented a rudimentary way to test that instructions take as long as the FUSE tests think they should. Hence discovered that the (HL)-accessing BIT, RES and SET weren't. Corrected.

Attempted to bring a common hierarchy to the Z80 and 6502 test machines, particularly with a view to eliminating the special-case Jam stuff on the 6502.

Made an attempt, flawed so far, to find a neat way for processor subclasses to offer bus management as an inline function.

Improved logging of bus operations and corrected placement of the OUT step in that repetition group; was otherwise outputting the wrong side of the B adjustment and therefore to the wrong port (if interpreted as 16 bit).

Made an attempt to introduce checking of bus activity against the FUSE tests. Appears to suggest 54 new failures.

Made an attempt to implement HALT as an operation that merely leaves the PC in place, adding the Z80's output line. Included that flag in FUSE tests. Discovered that it does not think that HALT acts that way. Which is probably correct.

Fixed Z80's ownership of its fetch-decode-execute program, its habit of scheduling invalidly when hitting an unrecognised operation and the test machine's habit of dereferencing invalidly.
