Still having issues with first iici. Got startup circuit working good. It chimes, but never get display. Also, if i hit button beside reset at startup i get an endless chime lol. Still a broken trace?

Very well could be a power supply issue. I say that because in a iisi a leaky power supply has sometimes caused this same error, do you have photos?

no, the psu works perfect on other machines. I have new 74hc132 and 74hc74 chips coming, hopefully will clear two iici boards up. The iici in this post also doesn't death chime when no ram is present, is that normal?
