Digital clock with 3 nos SAA1064

@PaulRB.

Sorry about the delay … I was on vacation. Yes that mistake is a drafting error. Attaching the correct method … I guess this is the right way. I do hope that pulling up the SCL and SDA lines to 3.3V is OK with the ICs themselves being powered up by 5V and 12V respectively ??

And yes the 1" displays work off 5V as their forward voltage is about 2.1V

Thanks so much !!
