Initial pass at implementing Alto Music (Organ/DAC interfaces). Not currently functional. Fixed Nova diassembly to properly handle alto-specific instructions; fixed some annoyances with microcode disassembler.

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.

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.

Fixed remaining disk issues; KSTAT bits 4-7 must always be "1," and head select change must reload current sector. Boot now loads in complete boot program and control is transferred to it.
