did you try hooking the composite output to a monitor to see that the computer did indeed boot?

That riser for Gary... you're sure that's installed correctly as per the notch? hehe

I just know that the lead coming off the Agnus board goes to pin 36 of Gary. But the notches on the socket (riser) should reflect that. Ensure the notch of the socket matches the notch of Gary. AND that ALL of the pins on that socket are in Gary's socket.

Just kidding!

Green flashes (normal if you have a Deneb USB card) indicate bad Chip RAM or... bad Agnus! Pull the old girl out and ensure all her tiny little pins are aligned and that your MiniMega Chip board is fully inserted. Really, really easy to accidentally bend those puppies removing her though, so no surprise there. Hopefully you have a nice PLCC puller and are not prying her out with tiny screwdrivers - ouch!

You can't use an 8375 or 8372AB Agnus in an A2000 without purchasing a board like you already have. I don't think the machine even boots with it installed. I gave it a try once and IIRC, that's what happened - nothing. Thankfully I didn't blow my mobo. lol
