/************************************************************************************************* Forte Card 1994, Fortex Ltd. Driver by Angelo Salese. Additional work by Roberto Fresca & Rob Ragon. Notes: - NMI mask and vblank bit are made thru SW usage of the I register (that is unused if the z80 is in IM 1). TODO: - fortecar requires a proper EEPROM dump, doesn't start due of it. - fortecrd has non-default data in the default EEPROM. English set: bp 512 do pc=53e Spanish set: bp 512 do pc=562 ------------------------------------------------------------------------------------------------- The Fortex company manufactured its first game 'Forte Card' in 1994. It soon became a favorite with the Bulgarian players. Improved versions were developed and were sold in Russia, Austria, Brazil, Argentina and the Balkan peninsular. In 1995, Fortex, first of all Bulgarian games manufacturers, exibited at the Plovdiv Fair a com- puter based version of Forte Card. The following years were times of hard teamwork, which resul- ted in a variety of products: centralized cash desk, on-line jackpot and a network control and management system for game centers. ------------------------------------------------------------------------------------------------- Forte Card (POKER GAME) CPU SGS Z8400AB1 (Z80ACPU) VIDEO CM607P PIO M5L8255AP snd ay38910/P (microchip) + 8251A RAM 6116 + GOLDSTAR GM76C256ALL-70 dip 1X8 ------------------------------------------------------------------------------------------------- Forte Card - By Fortex Ltd.

RTC V3021 Dip 1x8 Xtal: 12 MHz. NOTE: The CM607P IC is an exact clone of Motorola's MC6845P CRT Controller circuit from MC6800 family. Used to perform the interface to raster scan CRT displays. Made in Bulgaria in the Pravetz factory, where Pravetz-8 and Pravetz-16 compu- ters were made in 1980's. FULL equivalent to MC6845P, UM6845R, EF6845P, HD6845P, etc. The ST93CS56 and ST93CS57 are 2K bit Electrically Erasable Programmable Memory (EEPROM) fabricated with SGS-THOMSON's High Endurance Single Polysilicon CMOS technology. The memory is accessed through a serial input D and output Q. The 2K bit memory is organized as 128 x 16 bit words.The memory is accessed by a set of instructions which include Read, Write, Page Write, Write All and instructions used to set the memory protection. A Read instruction loads the address of the first word to be read into an internal address pointer. ------------------------------------------------------------------------------------------------- Game Notes... There are 3 keys for service modes: 1) The Owner Key. 2) The Rental Key. 3) The Credits Key. To enter credits through an operator: 1) Turn ON the Credits Key. 2) Press RED button to add x1000, or BLACK to add x100 3) Turn OFF the Credit Key. ------------------------------------------------------------------------------------------------- From the manual (sic)... Initialization of the Forte Card circuit board (Init machine) 1) Open the door of the machine, switch on the game and wait until the message 'Permanent RAM test failed' appears. 2) Turn the Main Control and hold it in this position. 3) Enter the serial number of the circuit board with the eight keys. 4) Press STAR key and wait until the message 'Machine initialization completed' appears. 5) Release the Main Control, switch off the game and close the door. 6) Switch on the game and wait until the demonstration displays appear. 7) Turn the Main Control, adjust the time. This is the last step of the initialization procedure. ------------------------------------------------------------------------------------------------- Edge Connector / Pinouts.... -------------------+--+------------------ Components Side |PN| Solder Side -------------------+--+------------------ GND |01| GND GND |02| GND +5V |03| +5V +5V |04| +5V +12V |05| +12V CUR.
