I have a new to me F-14 Tomcat that I get 10 diagnostic flashes. I do know that means there is a problem with U27 ROM or its associated components and connections. I replaced the ROM today and still get the 10 flashes. I removed all connections except 1J17 and still get the flashes. So now I am at the point that I need to check the associated components, but I don't know what they are. I have never worked on any system 11 boards.
I believe that the guide that I'm working with is Clay's guide, but it don't go into depth on this subject, other than working with a dead board. I do have a logic pin and a Radio Shack probe style oscilloscope and would very much love knowing how to work on this board.
I'm going to double check the power supply, but what should I check other than that?
