Several years ago, my wife purchased an Alpha Micro AM-919 backplane for me that she thought looked a great deal like it would work with some of my vintage systems. As I've been working with some S-100 boards, I've been eying the AM board and wondering about its usefulness with S-100. I've heard that some AM products will work, some must be modified, and some are not really useful. Does anyone have a set of schematics available, either PDF or hardcopy? I've checked with the Alpha Micro Phun Machine web site, bitsavers, and even contacted Alpha Micro directly (they no longer have information available on that type of system). Thanks! Brian.
