TurboSound Emulator (normal mode, not HI-Z)

Based on
AVR Emulator of IC AY-8910, AY-3-8910, AY-3-8912 for Atmega8,Atmega8A
Version 24.0 with speaker support (28.07.2016) Parallel mode only!

Uploading:

	Use avrdude and USBAsp programmer

        avrdude -p atmega8 -c USBasp -U flash:w:emul_240_turbosound_chip0.hex -U eeprom:w:Conf_parallel_25MHz_1_75Mhz.hex -U lfuse:w:0xCE:m -U hfuse:w:0xCF:m
        avrdude -p atmega8 -c USBasp -U flash:w:emul_240_turbosound_chip1.hex -U eeprom:w:Conf_parallel_25MHz_1_75Mhz.hex -U lfuse:w:0xCE:m -U hfuse:w:0xCF:m

files emul_240_turbosound_chip0.hex 	- Firmware for chip 0 with speaker port input at PD1
files emul_240_turbosound_chip1.hex	- Firmware for chip 1 with speaker port input at PD1


	Conf_XXX_YYMHz_ZZMhz.hex	- configuration file for emulator to write to EEPROM
		where XXX - standard, parallel or serial
			standard - use both types of connection parallel and serial
			parallel - use only parallel mode connection for using in real hardware (e.g. ZX-Spectrum)
			serial - use only serial mode connection (use RX pin on atmega8 with USB->TTL converter and AYPlayer or other software)
		YY - atmega8 oscillator frequency
		ZZ - AY chip oscillator frequency emulation 1_75 = 1.75MHz, 2 - 2MHz
