Implemented disk writes (roughly). Bravo now works. DIEX passes with writes enabled. Begun investigation into drive selection logic. Added Mesa source code with annotation, is displayed in ROM1 tab.

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.

Fixed display microcode and display controller. Alto display now generated 100% by microcode tasks. A few small optimizations.

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

Implemented temporary "fake" display controller which renders Alto DCBs to the screen, bypassing the display microcode. Alto is booting! Rough keyboard implementation.

Initial rough implementation of Display hardware and associated tasks. Not really working.

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.

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.

Built basic debugger UI and execution framework; a few bugfixes. CPU now executes uCode up until the first STARTF (unimplemented).
