His Nibbler implements a 4-bit CPU using 7400 logic chips ... That’s a feat considering this is still just a design idea. It was made possible because he wrote a simulator based on the design.

Design of logic machines. Finite state machines, gate array designs, ALU and 4 bit CPU unit designs, micro-programmed systems. Hardware design of advanced digital circuits using XILINX. Application of ...

The AMD chips provided a 4-bit data path that could be chained ... That’s how you’d typically design a bitslice CPU. An AM2909 , AM2910, or AM2911 (microprogram sequencers) would address ...

Yes, over half a century ago now, the Intel 4004 appeared in all its 4-bit glory (with its successor being the Intel 8080, later leading to the famous 8086 processor, ushering in the x86 era).
