/************************************************************************************* /\/\<< Kasino '89 >>/\/\ 6-players electronic roulette. Video field + phisical LEDs roulette. Driver by Roberto Fresca. Running in this hardware: Kasino '89, SFC SRL, 1989. Osel '93, SFC SRL, 1993. Special thanks to Rob Ragon and Tomasz Slanina for their invaluable help. Also big thanks to Iris Falbala and Sofia Kiara for the beta-testing stage. For better results, use the associated artwork. Will allow you to see the roulette with all the working LEDs and lamps... ************************************************************************************** Hardware specs: Seems to be a MSX2 system on steroids... 1x Potted CPU box (1x Z80 @ 3.578 MHz. + encrypted program ROM inside). 1x Z80 (audio) @ 3.578 MHz. AY-3-8910 @ 1789 kHz. 1x Unknown metallick brick (Yamaha MSX2 VDP inside). 1x 8 DIP switches bank. 1x Xtal: 21.477 MHz. 1x Plastic roulette with 37 LEDs NOTES: - Addressing and data lines are fully scrambled inside the epoxy CPU box. Also there are PLDs connected between them. - Another board has both Z80's running at 3.336 MHz., but we strongly think that they tied a 20MHz crystal due to lack of 21.477MHz ones stock. - You can see the scrambling stuff inside the CPU box through a X-RAY picture, and other reverse-engineering steps here: http://www.robertofresca.com.ar/ ************************************************************************************** Tech Notes... - NMI of main Z80 is connected to a 138Hz. oscillator AND bit6 of port $82. That means NMI should be triggered each 138Hz. *only* if bit6 of port $82 remains active. - NMI of second Z80 is connected directly to a 138Hz. oscillator. - INT of second Z80 is coming from 2 places: The HOLD/ASSERT (flanco descendente) is done by the main Z80 through IO port &85, and the CLEAR part (flanco ascendente) is autogenerated using the IO port $00. - The AY-8910 is clocked 1789 kHz, and has nothing connected at simple sight. ************************************************************************************** Roulette's LEDs Support. ----------------------- Ports $83/$84 handle the roulette's LEDs in a multiplexed way... Port $84 is the selector, while port $83 carry the LEDs set.

'-' Whilest in Audit/Test mode, pressing the ADVANCE button, you can enter into screen and inputs test mode. This ADVANCE button, is routed into a latch with D0, sharing with BET button. ************************************************************************************** Game Notes: ----------- You have 3 controls for operators. The Operator/Habilitation Key, the Audit/Test Mode switch and the Advance button. To enter the game, you should turn the Audit/Test switch ON, then OFF, otherwise a louder and annoying alarm will warn you about. Once in game, you need to turn ON the Operator/Habilitation Key to allow credit IN and OUT all 6 players. If the key is OFF, the IN/OUT credit system will not work, getting the game only in attract mode. * Audit/Test Mode There are 2 controls inside the cab: 1x Audit/Test Switch. 1x Avance Pantalla (Advance) button. In the disclaimer, turn the Audit/Test Switch ON. You can see a screen with all the bookkeepings. While in Audit mode, you need to press the ADVANCE button to enter the first test. Black screen. All roulette LEDs ON. then... White screen. Test all sequenced LEDs in both ways, when pressing the CREDIT IN/OUT buttons. You need the Habilitation key ON to do this test. Press ADVANCE again, and you'll see the color palette screen. Press ADVANCE again, and you'll see the grid pattern screen. Press ADVANCE again, and you'll enter the input test mode. All control buttons from each player, including Credits IN/OUT will be shown here. Press ADVANCE again, and you'll arrive to the Audit screen again. To exit the Audit/Test mode, turn OFF the Audit/Test switch. you'll enter the game. ************************************************************************************** TODO: - Check why some sound events are louder than others (volume balance?). - Fix NVRAM. - PCB layout. *************************************************************************************/ #define MASTER_CLOCK XTAL_21_4772MHz #include "emu.h" #include "cpu/z80/z80.h" #include "sound/ay8910.h" #include "video/v9938.h" #include "machine/nvram.h" #include "kas89.lh" class kas89_state : public driver_device { public: kas89_state(const machine_config &mconfig, device_type type, const char *tag) : driver_device(mconfig, type, tag) { } UINT8 m_mux_data; UINT8 m_main_nmi_enable; UINT8 m_leds_mux_selector; UINT8 m_leds_mux_data; UINT8 m_outdata; /* Muxed with the sound latch.
