How do I simulate a 74LS74 FlipFlop using NGSPICE 41?

This forum has some threads with lots of ngSpice examples, including the 74ls74:

Simulation examples for KiCad/Eeschema/ngspice

Attached you will find some simulation examples for audio amplifiers, oscillators, power supplies, and other circuits. All have been designed/tested with KiCad 6.0.2 / ngspice-36 or KiCad 6.0.10 and ngspice-38. All will run with internal ngspice, Inspect → Simulator → Run —> Add Signals some (Tian probes) will require an additional external ngspice (mostly for its more complex interface and output capability) File → Export → Netlist… → Create Netlist and Run Simulator Command after having …
