Starting off with a SUBCIRCUIT for a 4046 PLL
OK we can post circuits that work better or that use parts with the same exact functionality as what stan meyers intended in his schematics.
For example... cd40163be counter binary synchronous used in figure 2 to set the timing for the cd4067 multiplexer chip is no longer available
obsolete... so use cd40161be, same functionality when wired ( tie pins 1, 3, 4, 5, 6, 7, 9 & 10 to VCC) pin 8 is zero volts 11,12,13,14 are ABCD respectively
Stans original Figure 2 circuit was designed with optoschmitt redundancy built in, so he used 2 mux chips...if we wire it correctly we only need one MUX chip
posting figure 2 circuit further down...soon

between you and Tony are all the circuits on here but ive tried to put them together and lable most everything so heres a clean figure 12 with everything labled:

Here is Figure 8. Resonant Scanning Circuit verified by the actual Stan Meyer Vic Card Photo
There seems to be some question on the actual value of the Capacitor between pin 6/2 and ground on the 555 timer.
it could be 10u or 1.0u...Don has stated that it is a 10u
maybe build it with a mini selector switch on the PCB and have both for different scan rates
The purpose of this part of the circuit is to provide the 4046 PLL chip with a variable voltage on pin 9 for a lock signal to be scanned for by the pll VCO
the measured range of voltages can be determined with a virtual voltmeter on the manual adjustment / resistor divider network by placing the Manual / Auto switch in Manual setting, because the VIC CARD photo gives us the resistor values that he used and we also know the POT was a 50k ohm
Viola ! we then know the VCO parameters he needed by inference from the manual adjustment section...
We Can Do IT !

Here is Figure 12, ready to go
notice the cool graphics...seems this circuit likes to divide the outputs by two !
good for one simple pc board including a 7805 voltage regulator.
moving right along...

Here is the figure 2 simulation based on what information is available so far
This circuit contains a custom 74122 subcircuit by using the pins from a 74123 in the multisim library and adding extra pins as in the datasheet for a 74122 by adding a few extra logic components... any engineers out there feel like challangeing my design please feel free to post a modified 74122 subcircuit if mine is incorrect
Thanks
( you can view the subcircuit by double clicking the 74122 subcircuit component in the figure 2 simulation file)
also:
not sure on how many signals came from the distributor
i believe there were two breakout cables coming off the distrbutor
one for the 4 injector signals and possibly another with more for RPM sensing
How this affects the signal that is output is beyond me
also i may have the 74LS112 hooked up wrong on A1 for pin 9 destination...
-
here is the 3 and 4 schematics
only one change from dynodons values and accurate according to the photos
the change is the 10u cap becomes a 1nf ( just below Q3) to get an output waveform just before the switch that actually does something in the rest of figure 4
at least thats the way i was able to get the simulation to work......
-
I have pulled my hair out over that sim.... i still cant get anything out of the second half of the 7402.... i had it working with one half of the 74123 but now back on the dern 7402 ughhh !!!!!
-
but here is the best file ive found on the 122 n 123
-
hey Ali ... i have the 74123 working its just so slow on my end that to see the adjustment changes you have to restart the sim.your sims are allways much faster than mine for some reason.

I'm searching a TIP120 model for Multisim.
For the Resonance/Resonant WFC "cell driver circuit" and "voltage amplitude control".

Nobody?
In my opinion it is essential for the Unipolar Pulse generation at the secondary coil.

Found this old spice model, not sure anymore if it was working, try creating a component with it in multisim ....
