RE: [N8VEM-S100:3415] ALTAIR/IMSAI 8080 CPU replacement board

Hi Group,

Well, now that these "Sea of PTH" buffered prototype boards are built, my first project on one of them is the 8080A CPU replacement board I started talking about back in November. 

I have the prototype built (for the most part).  I plugged it in, but it's not working... yet.
But at least I'm at the trouble shooting stage.
