Apple IIGS RGB Monitor, does it display anything without a video source?
I have a Apple IIGS RGB monitor no cable or computer to test it with. I just want to sell the monitor at this point. I don’t recall in the past if this monitor displayed anything when it was powered on just lit up with when there was no video source. I just don’t have the room to keep it and want to test it out. Since I have no way to get video is there a way to be able to test the monitor. That is does it show raster to something when powered up without a video source. I don’t recall what my old monitors did without video. I don’t think I remember turning them on without video. Would I assume that is should work if the power light comes on but no picture(no video source) or should it at least have raster(white or some color screen)?
