I just went through every possible control code for decimal point placement on the (now obsolete) Motorola MC14489 with spec sheet in hand. I thought the chip was defective but found Futurlec part number 7SEG4RCC could not properly display decimal points in every digit. I swapped in display 7FG3641AG and now every thing is working as advertised.
