I have a GORF which just died.
I'm hoping there's somebody that might have some insight to troubleshoot this game. I have both manuals, the original GORF and the Card Rack System to help lookup anything. I'm full of questions right now and not finding enough answers online.
I checked the power supply and all voltages are there, +5V, +12V and -5V. I even checked the +5V directly on the CPU card across the 0.1uf caps. The RESET line out of the power supply is a HI level = 5V. The schematic says this a an Active LO signal, meaning it should pulse LO to reset the processor and return back to a HI Level. But I don't see anything on the monitor screen. As far as I remember it's supposed to talk when the game is turned on, but it doesn't.
Wasn't there a website which provided some tips to troubleshoot bad problems like this in a systematic way to locate the bad card when you have several cards in a game ?
Does it really need ALL 6 cards just to bootup and display anything on the monitor ?
Is it possible to just plug in say the CPU card and RAM card to see something on the screen ?
I tried some extra card racks --untested after several years-- that I have here and they all exhibit the same thing - absolutely nothing at power on. I was hoping I would get different symptoms between them. Something that would get me started in repairing this game.
