/* Description: Mockingboard/Phasor emulation

// History:
//
// v1.12.07.1 (30 Dec 2005)
// - Update 6522 TIMERs after every 6502 opcode, giving more precise IRQs
// - Minimum TIMER freq is now 0x100 cycles
// - Added Phasor support
//
// v1.12.06.1 (16 July 2005)
// - Reworked 6522's ORB -> AY8910 decoder
// - Changed MB output so L=All voices from AY0 & AY2 & R=All voices from AY1 & AY3
// - Added crude support for Votrax speech chip (by using SSI263 phonemes)
//
// v1.12.04.1 (14 Sep 2004)
// - Switch MB output from dual-mono to stereo.
// - Relaxed TIMER1 freq from ~62Hz (period=0x4000) to ~83Hz (period=0x3000).
//
// 25 Apr 2004:
// - Added basic support for the SSI263 speech chip
//
// 15 Mar 2004:
// - Switched to MAME's AY8910 emulation (includes envelope support)
//
// v1.12.03 (11 Jan 2004)
// - For free-running 6522 timer1 IRQ, reload with current ACCESS_TIMER1 value.
// (Fixes Ultima 4/5 playback speed problem.)
//
// v1.12.01 (24 Nov 2002)
// - Shaped the tone waveform more logarithmically
// - Added support for MB ena/dis switch on Config dialog
// - Added log file support
//
// v1.12.00 (17 Nov 2002)
// - Initial version (no AY8910 envelope support)
//
// Notes on Votrax chip (on original Mockingboards):
// From Crimewave (Penguin Software):
// . Init:
// . DDRB = 0xFF
// . PCR = 0xB0
// . IER = 0x90
// . ORB = 0x03 (PAUSE0) or 0x3F (STOP)
// . IRQ:
// . ORB = Phoneme value
// . IRQ last phoneme complete:
// . IER = 0x10
// . ORB = 0x3F (STOP)
