What system(piggyback/standalone) if any is out there to run ignition only on a rotary engine?

I have a 4 port 13b carbed, I want to use direct fire ignition using the CAS from a 2nd gen. Is it posible? or better yet what are my options for making this happen. I'm at my witts end and have searched repeatedly and found nothing that solves my problem. I have everything I need except for spark. I'm at the point now where I will try almost anything to get this car started.

 

ignition-only computers? yes, they exist - try Haltech. however, i'd recommend searching DLIDFIS in the Gen I section and archive first - there are many good threads showing how you can make your own direct fire ignition out of Gen I and Gen II parts. i've never done it, but from the posted results i've seen, it seems to not only be effective, but also very reliable.
