I have a SAA5284 on my card. According to the data sheets it should
have an I2C bus and normal IO ports.
Looking at the signature of my card I can't really find the chip on
the I2C bus.
I have:
0x80 = MSP3400C
0xA0 = EEPROM
0xC2 = Tuner
I tried your txt program, but have no success getting any
teletext page :-(

Frank
