If you "have spark", can't be anything about the dist or "timing" keeping it from getting fuel.
Pour a little gas into the intake; if it's a fueling problem, it should run until that fuel runs out.
Make sure you have the dist sending spark to the #1 plug at #1 firing, NOT at the OTHER instance of #1 TDC during an engine cycle which is when the #1 exh stroke is ending and its intake stroke beginning, and #6 firing.
Put the original PROM back in and see if it at least runs.
Once you get that far, swap PROMs.
One change at a time...
Logic. Reason. Patience. ;)
