How to put a Cube (and I assume, Mac Mini) in a CC
Even though I have a DM-10 Pisces monitor that Greg Younk used for his cube-in-a-cc-hack, I am always drawn back to the challenge of working with regular analog boards both for the challenge and because it's more useful to more people- Pisces monitors appear to be rare and LCDs are expensive. After the mini came out I returned to the lab to see if I couldn't get my cube to sync with a CC analog board, which had failed in the past.
Turns out the problem was that I was trying to outsmart the cube. I tried to use an Apple DB15-HD15 adapter and modify the sense lines, but I was never able to get it to work. What got it to work was:
1) hooking up only the video, video grounds, h/v sync (tied together) and sync ground, leaving the sense lines unattached and
2) using the resolution switching trick mentioned for the iMac-CC hack. Since OS X defaults at 800x600, you need a way to switch it to VGA with a trick of some kind. The iMac-CC page recommends SwitchRes, I use a shell script (cscreen) tied to a function key through Xkeys. Previously I had thought the whole thing didn't work because my CC has given me 800x600 before with a 575 m/b, so I thought I didn't need to worry about the resolution switching trick. But for some reason it won't sync at that resolution with the cube.
And as I discovered quite a while ago but will remind here:
3) brightness and contrast are controlled this way. I run a 5v line through the control knobs of an MCD monitor.
Now, that's just for VGA. Most people prefer SVGA, and although OS X is perfectly useable at VGA, most people seem to think otherwise. So I kept working at it, and found a solution, the good ol' Macintosh Color Display (M1212). I first tried an LC575 a/b, which I feel gets a slightly better SVGA picture, but I was never able to get it to sync. The MCD will sync at SVGA@56hz, but *not* at VGA@60hz. The procedure is the same; just hook up video and sync lines/grounds, but no sense lines. Even after adjustments, there will likely be some distortion of the top few scan lines, and I have 1 cm borders around the raster area. It's up to you to decide you like a larger area with fuzzier convergence (requiring a yoke transplant) or a smaller area but crisper image.
I assume that this would all work with a mini, unless going through a DVI-VGA adapter changes anything. I'm surprised that in all this time that the mini has been out no one has done this hack, I wish I could do it but I have no need to buy a mini right now, and money is too tight to do it just for glory. But I think a cube in a CC makes an excellent, useful hack, allowing up to date speeds and operating system without having to spend the money for an LCD.
Here is some information and links for resolution changing that might be helpful for iMac-CC conversions as well.

VGA Applescript (if script is in directory /Applications/):
do shell script "/Applications/cscreen -x 640 -y 480 -r 60"
. . . scanning eBay recently, I saw that Cubes have take a real price hit because of the Mini . . . . .
