Descreet Logic VFD Clock

[TheEPROM9]

For quite a few years now I have been working on a VFD descreet logic clock. The chalenges have been designing my own custom multiplexer (Best way to learn about multiplexers). Also the clock section of the circuit. I have now finished the multiplexer design and need to finish building it. Also still need to design the clock part of the circuit.

Thought people on the Blog would be interested plus advice and pointers would be very helpful, espeshaly in the clock section. 

Also I have a nice retro setup.
