I will look into it, I doubt it though since the display I was using was though an external cable so I adjusted the external monitor to get that picture up. What does a lisa do without the keyboard/mouse/HD/disk when you turn it on? I still do not know if my I/O board is complete. for example the R41 resistor appears to have been cut off the board compared to the other factory left off parts. (forgive my spelling errors I am horrible at English and have not slept in a while ) I do know that the cpu board is most likely to work since I have two of them I can switch out and they both do the same thing so unless they both have the same problem its not there.
