amusco: Major improvements; promoted to WORKING
- Inputs figured out almost completely - Add blinking cursor for service mode - Gross hacks used to get coins working due to broken IRQ timings - Palette remains in dire need of improvement Peripheral emulation improvements (nw): - mc6845: Allow cursor blink state to be read - pit8253: Eliminate device name from logging messages
