I found that same C-code and I guess the majority of the info. I bought the PCB's from Martin and I know he has his own programmer. It shouldn't be too dificult, but having the exact specs is of course crucial. I sent a mail to some service department @Tesla,let's see what happens. From what I have found I expect it to be 10.5V, but then there might be more requirements as the amount of current to burn that fuse and the duration for the current. I guess, but I'm far from an expert, it should be simpler here than burning an EPROM, as it is a different technology.

Polished up some of the datasheets I found, some have more pages than others, but I keep all stuff. Happy to add these to this thread.

I only have the complete binaries (old and new), from Martin, but I was already thinking of how to split over two 74S571's, so it would be handy to have your split binaries. Maybe you can add these to this thread so everyone can access that info?
