RE: Building a clock the hard way
I still use a seven segment LED alarm clock I built more than 40 years ago it is based on a LSI clock chip as is the nixie clock I built more recently. The clock chip I used in the nixie clock has multiplexed seven segment outputs which I converted back to BCD and demultiplexed to drive the 4-10 nixie driver chips. I have vintage CT7001 and MK5017 clock chips here waiting to be turned into clocks as well.
