Apple Color High-Resolution RGB CRT Monitor

AppleColorTM High-Resolution RGB Monitor from 1987. I have no idea if it works, when I turn it on the power light comes on. I tried using various adapters, but I can't get an image from my PC clone, only some lines and static. I think these monitors are only compatible with Macs from that era anyway. Primarily looking to trade for any VGA CRT monitor, but feel free to make an offer otherwise.
