Walter, looking at CT27G5B schematic pins 5 and 6 of the eeprom both have a 4.7K pullup resistor connected to the 5v source. Looks like they should sit at 5 volts and have negative going data and clock pulses when buttons are pressed just like the RCA sets, probably the same eeprom. Pins 1,2,3,4 and 7 are grounded. Your data and/or clock lines are probably being pulled low by something on the I2C bus. Jim Myers Since 1972 Telrad Electronic Services Co.
