DIS with 749.bin success

[Mike Pitts]

Hi,

Can anyone tell me what kind of signal the HEI 
module in the 4.3L Chevy distributor outputs?  
I would look for myself if I could, but I don't 
have an o'scope.  :(

I'm wondering if I can just use the signal that's 
already there for DIS, perhaps altered/buffered by 
some sort of cheap/simple electronics.

Bruce, I'm sure you know. :)

This could save some time by avoiding the fabrication 
of the mechanics/electronics of the distributor.

BTW: Does anyone know of a decent place to find used 
o'scopes for sale, cheap? 

Thanks,
-Mike
