Electromotive sells a waste spark system they call "XDi" that seems to be the go to replacement ignition system for the earlier carborated Ferrari folks. Perhaps something to look at if you haven't already?

If you've got any Fiat friends who have a car with a Digiplex ignition system that needs a replacement, my ignition units will work with many of them as well, as the Fiat units are basically identical to the Ferrari units but with different curves in them. I've never actually sold a unit to a Fiat customer, but I do have curve information on several Fiat and Lancia cars. The exterior boxes are 100% identical, and I've used some of the Fiat boxes as cores before (I use the old boxes to make the new units, as sandcasting new replacement aluminum boxes would be way too cost prohibitive)

I've heard good things about those distributors, but I've never played with one myself. I've used the Petronix solid-state triggers to replace points in a distributor plenty, but several of my mechanic friends now use the 123 ignitions instead.

Don't even need Pertronix. You can use a TFI module from 1990's Ford vehicles and trigger it directly from the points distributor, or build a simple circuit with 1 transistor to invert the signal and trigger an HEI ignition module.

This is true, but the Pertronix units are cheap, easy to install, easy to remove and put points back in, and readily available. The downside I've found from them is that their reliability isn't perfect, but they're definitely better than points!

An OEM TFI or HEI is even cheaper and more reliable. If you splice everything with bullet connectors and keep the points coil with you, it's the same thing to go back to points, with no tools.
