+ * cpc_ssa1.h -- Amstrad SSA-1 Speech Synthesiser, dk'Tronics Speech Synthesiser
+ *
+ * Created on: 16/07/2011
+ *
+ * Amstrad SSA-1 - SP0256-AL2 based Speech Synthesiser and Sound Amplifier
+ *
+ * Uses on-board resonator, clocked at 3.12MHz
+ *
+ * Decodes only I/O lines A10, A4 and A0
+ * Official I/O ports:
+ * &FBEE (read)
+ * - bit 7: SP0256 Status 1 (SBY)
+ * - bit 6: SP0256 Status 2 (/LRQ)
+ *
+ * &FBEE (write)
+ * - bits 7-0: SP0256 Allophone number (must be 0x00 to 0x3f, however, all data lines are hooked up)
+ *
+ * &FAEE (write)
+ * - same as above, used because of a bug in the driver software, but still works due to the way the I/O ports are
+ * decoded on the CPC.
+ *
+ * More info and PCB pics at http://www.cpcwiki.eu/index.php/Amstrad_SSA-1_Speech_Synthesizer
+ *
+ *
+ * dk'Tronics Speech Synthesiser - SP0256-AL2 based speech synthesiser
+ *
+ * Uses the CPC's clock of 4MHz from pin 50 of the expansion port, gives faster and higher pitched voices than the SSA-1
+ *
+ * Official I/O ports:
+ * &FBFE (read)
+ * - bit 7: SP0256 Status 2 (/LRQ)
+ *
+ * &FBFE (write)
+ * - bits 5-0: SP0256 Allophone number
+ *
+ * More info and PCB pics at http://www.cpcwiki.eu/index.php/Dk%27tronics_Speech_Synthesizer
