Not saying he didn't do it, not saying he wasn't a computer guru, just I doubt he had an electronic computer doing the job. Probably some sort of mechanical device. A computer, by definition, doesn't have to be electronic. In the early days, a computer was the person operating the device.Flash, you got it exactly, good thing some drivers are just better at it than others. BTW, I saw a guy named, John Burke, at a big drag race in Englishtown, N.J. have it in his A/D rail he was a computer guru, even back in 1961, it would begin shorting cyls. out when rear wheel speed reached a certain % faster than the fronts.
