OK, hopefully I have this in the right spot now 
Hi all,
I've been trying to fire up my dig dug board and it has some issues....
I have rebuilt the ARII, then measured the voltages.
The 5v line was pretty spot on 5v and the other was 11.7v or something like that.
I measured at the 5v line at the connector, test points and the IC's and am getting a solid 5v.
The connector also looks good.
The first picture is what I'm getting on screen and the second picture is what I get when I pull the Z80 out located at 6K.
Dig Dug has 3x Z80's, so I did try all 3 in all 3 sockets to see if I could get something to change, but nothing.
I've removed, cleaned and reseated all socketed chips, but there was no change.
Has anyone seen these screens before ??
OH and don't mind the "checked & ready that's written on the screen, it was like that when I bought it and haven't cleaned off yet.
