I decided to see what this weird machine is all about. The HDD had failed so I switched it out to a 2.5" SATA drive and reinstalled Windows XP.
I also installed the video and touchscreen drivers.
I tried to recap the PSU but it was a bit of a mess and decided to leave it alone.
Here are the drivers for the video card and the touchscreen controller.
The machine will take 2 x 1Gb 184-pin 1GB PC2100 266MHz DDR Non-ECC CL2.5 PC RAM for 2Gb total.
