New hardware implementation:
...
- Orbit controller: implemented and passes ROS-less diagnostics
- ROS: In progress, not functional
- DAC: For Ted Kaehler's Smalltalk Music system (FM and Sampling). Works, generates audio and can capture to WAV file.
- Organ keybard: Stub, enough implemented to make the music system happy (so it will play back music and not crash.)
Some minor cleanup.
New dependency on NAudio package for DAC playback. Installer updated to include NAudio lib.

Minor performance improvements. General cleanup. Fixed major (but subtle) issue with memory state machine (BravoX now works!). Updated readme and installer for 1.1 release.

General code cleanup. Fixed debugger display of RAM banks for 3K systems, cleaned up logic for displaying ucode memory. Implemented memory timing for Alto I systems, incorporated Alto I uCode ROMs from Al K, which now boot. ST-74 runs better now.

Fixed drive select logic (multiple drives now work properly -- fingers crossed) and some minor cleanup and dead-code removal.

Fixed S register addressing (many things now working!), tweaked display (mouse displays correctly in lowres mode). Added support for committing disk changes back to disk images (done automatically when switching disks or exiting). Repaired BravoX image.

Ethernet implemented, fixed a bug in "mixed" double word stores (store followed by fetch rather than two stores). Fixed a few UI issues, fixed Reset behavior.

Implemented proper video timing, basic mouse support and fixed microcode RAM loading. MARTEST now passes with flying colors; more things are running. Suspect disk timing for other failures.

Minor bugfixes, introduced a new timing infrastructure and moved DiskController over to it. Minor performance improvements; now running at 110% speed. Display timing is still too slow.

Support for CRAM reading/loading, SWMODE support. Rough debugger UI for viewing / disassembling microcode in ROM1, RAM0 banks (ugly). Minor performance improvements.

Fixed: Disk address (KADR) and Disk Data (KDATA) registers behave (more) correctly; in particular record commands hare processed properly and KDATA handles reads/writes more sanely. Fixed checksum calculation; due to above changes microcode now correctly validates checksums and boot progresses to read in an entire track's worth of data before dying with a "check failure" error.

Some fixes to emulator task dispatch functions, added Nova disassembler, nova instruction single-step and nova instruction breakpoint support. Penciled in DNS (Nova Shift) support in emulator task. Added skeleton for Logging.

Disk sector reads now work correctly, and checksums are correctly calculated. Still feeding dummy sector data.

Refactored Task code into separate files for readability; added breakpoint support and basic Memory window to debugger. Initial implementation (mostly stubs) of Disk hardware and Tasks.
