I've got all of the components installed on my board, and have put together (on a separate PCB) a circuit for the video out RCA jack. (basically this circuit just extends the +5, gnd and video signals onto a small PBC with header connectors).
When I power on my Apple clone, should I see anything at all even though I don't have a keyboard or any way to reset or clear at the moment? I've read that some people see a screen full of "@" symbols, but I see nothing but a gray screen.
Do I have to have the reset and clear circuits/keyboard hooked up before I can expect to see anything other than a gray screen?
