Bus address and data seem to be alive but no serial, flag or sense activity. I am suspecting the CPU itself as it is a pull from an old S100 board that looks pretty rough. I'm ordering more INS8060s but they won't arrive for a while. Might you by chance have one you could sell me? I could give you another back when they arrive. Otherwise, this is a great project and I thank you for doing this. It brings back a little history that was in a better time for technology.

Hi Ray.=C2=A0 NIBL uses two 2716 eproms. Usuallh )n the forums y= ou can find someone locally to program eproms for you. Or you can can send = me eproms and k will program or you can buy programmed eproms on my tindie = site
