I'm using an AP1200 as a cheap quiet server and P2P computer. I don't have the pinout of the VGA port in front of me, but I will post back with it later.
I upgraded the RAM to 512MB and the hard drive to 160 GB. It's running Windows XP. Installing it was a little tricky because the video card flakes out about half way through installation. You can either make an unattended install CD, or plug a video card into the PCI slot while you install windows. The built in video card is fine after Windows is installed. If you want to use the TV output, you'll need to use the set top box video driver (I copied it from the Akimbo hard drive). Unfortunately, this driver uses strange sync timing that doesn't work well with a VGA monitor. Also, remote desktop won't work when using the Akimbo video driver. The most recent thing I did was to edit the BIOS to enable some hidden options. The most useful one is the CPU FSB speed. It runs at 800 MHz with no problems. There's also an option to run the RAM at 133 MHz, but it won't work at 133 due to their choice of clock generator.
I was never able to get the TV output to look very good. It appears to be running in 16 bit color (lots of color banding). It looked fine when it was booted to the Akimbo software, so there must be some configuration for the TV scan converter that's missing. It would also be nice to find a way to use the IR remote.
I have a few IP1150's that I would love to be able to use. With a new BIOS I'm sure it would be a useful computer. I experimented with flashing the BIOS, but I couldn't find one that worked at all. The existing BIOS looks completely non-standard.
I will see what I can do once it gets here. Gee I sure wish I could get the VGA working on my AP1200...hint...hint.
