I also added the old Amiga logo, and the Famicom logo.
I was not sure about the Famicom logo, but it appears on some consoles:

I could of course make a logo that says: "FAMILY COMPUTER", but I try to avoid text in the logos. That is why I prefer to use a picture of a Game Boy Advance than its official logo (just text).
I still have to find a solution for consoles such as the Playstation 3 and the Sega Mark III. The problem is that if we want all the system logos to be 40 pixels high, so that they match the Insomnia logo, they may become extremely long. Sure, I could reduce them and put them in a 40-pixel-high frame, but I don't like this solution.
But I think it would be possible to reduce the size of such logos if we use another Insomnia logo. For example, in the attempt of an Insomnia logo that I made with an eye, the height of the logo is still 40 pixels, but the height of the text is smaller. Then it would be fine, I think, to reduce the height of the logo, so that the texts "Playstation 3" or "Mark III" and "Insomnia" match.
