Aesculapius Posted July 11, 2016 Share Posted July 11, 2016 I dropped tears of joy. Thanks. Of notice, he is using a very basic oscilloscope and ROM dumps analysis to do the whole thing unless there is more in the video we don't see. Normally signal analysis would require a logic analyzer, so probably , the communication protocol is known beforehand; in such a case all you need to do is identify signal pins, synchronization signals, voltages and ground to plug to a right interface meeting the specifications. Its of course easy say it than do it, because if you don't know the cpu specifications which is mostly the case as these are custom, the you need to dig out all of this information from scratch, which can go as far as chip decapping to figure out the internals of these IC's. Fortunately ROM chips were separate from the CPU and you could access it without disturbing it (as it is even today in many cases). Link to comment Share on other sites More sharing options...
