Hello everybody,     maybe this is not the right forum to ask this, but this is one of my last desperate attempts...   I have a W&G PS-19 with the CPU board of the new type, with just 2 EPROMs.  See this picture : https://dl.dropboxusercontent.com/u/15089947/CPUBnew_2small.jpg  You will notice that one of the two EPROMs is missing  I found a CPU board of the old type, with 6 EPROMs of lower capacity.  https://dl.dropboxusercontent.com/u/15089947/CPUold_small.jpg  My question is : are the two, at the edge connector level, equivalent ? Can I put the old board in place of the new one, that with the missing EPROM ?  Or better yet, does anybody have the missing EPROM image he can send me as a file ?  Thanks,  --
