Reply To: Atom Red Ignition Module

[Mumbles]

I have a bunch of the Sierra modules on hand along with Atoms and the Sierra ones in the blue and white boxes are marked ‘Magnatune Made In W. Germany’ while the ones in the older red and white Sierra packaging are marked ‘ Atom Computer Ignition Sydney Australia’. The instruction sheets included with both modules are identical to the Atom instruction sheets except for having Sierra printed on them. They all have to be one and the same. The only difference I can see between the Sierras and the original Atoms is the packaging. Sierra P/N 18-5100 is for one module while P/N 19-5101 is for two modules.
