I'm trying to get my Amiga 1000 up and running.

I have a keyboard, mouse and S-Video adapter connected. I removed the front 256K expansion.

When I power it on, I only get a solid orange screen. I looked up the error codes and orange isn't listed. But red is. If I adjust the color all the way up, it looks more red. So the orange may be a result of my S-Video adapter (it's not a 520).

If it's actually red, then I believe that is a bad Kickstart ROM. But I'm not sure this Amiga even has a Kickstart ROM. I thought that was loaded by disk?

The power LED appears to be solid and doesn't blink.

Also, I checked some voltages. It appears Agnus (8361) is only getting 3.9v on VCC. The CPU, Paula and Denise appear to have 5V. I also checked the power on the floppy drive and I'm getting a solid 5V and 12V.

I might be able to find another Agnus from an Amiga 500 if you think it would be OK to swap.

Oh, this Amiga 1000 also has that "riser" card attached inside. I'm not sure if all 1000's had that. I have not removed it yet because it appears to be PITA to reconnect.

Any suggestions would be appreciated.

Oh, this is NTSC version if that makes a difference.

Thanks!!
