Hi Charlie..
You are absolutely right...as I see it, my ignition board will remain the same. I want to use a small timer board like the 2nd last one we all experimented with. It works well with Nyemi's hex file so why not use it. About the only deviation from standard will be to include the extra hole on my board to switch the resistor from negative to positive for those who will use mechanical advance for timing. I will annotate all changes as I prepare the final board..as it is now, it is easy to unsolder one leg of the resistor and poke it into another hole. Nuff said.

I just got a shipment of new toroid cores..from Amidon Associates on Ebay. The part number for them is T50-6 color coded yellow.
A buck apiece. Someone could probably find them cheaper but I just wanted to see if they were indeed what I was buying before from Ferroxcube and they are. Started winding the next set of ten toroids today so I can send them out to whoever needs one already wound with feedback and primary winding all done, ready to solder to the boards. I am also looking into a commercial company to etch the boards for me.. getting lazy I guess...no it's more like I don't have the spare time with my job now.
Being a motorcycle mechanic and with summer coming, the shop sure is busy!

Glad to see everyone is still interested. I never quit on these, but am to the point that we need the info all in one place, so yes, maybe a new thread or site. Let's see what the future holds with my programmer and fixes to the existing board first.
