So it's been a while since I had the Amiga 1000 on the bench.
A few years ago, I swapped the CPU, Agnus, etc. IIRC, just about every custom IC with a known working one.

The problem is that it boots to a single colored screen (RED). However, I would say it's ORANGE but all the docs say red. So maybe it's my monitor.

Not even the floppy drive will make a noise. Which makes sense. If red is a bad ROM (or something with ROM), then perhaps that's why it doesn't attempt to load anything.

Anyway, I'm running out of ideas here. I tested the voltages around the board and they look good.

My Amiga 1000 is a REV A board that has the daughter card on top. I think that's the WCS card. I pulled the WCS card out, cleaned the pins and even recapped it. Nothing. Just an orange (er, red) screen.

Keyboard LED comes on/off but after a while, just freezes.

Any ideas what to check next? I have working Amiga 500's and a working Amiga 2000 to swap parts if needed.

I also have a Kickstart disk.

Thanks for any suggestions.
