I originally got the machine for free with a faulty Unicorn socket 7 motherboard (it had everything else required including the IO board for it), and it turned out a standard 810 board booted the machine. What I ended up doing was copying opsetup.so to idle.so (after renaming the original) so it would go into service mode and I was able to recalibrate the touchscreen (which when it was malfunctioning, kind of acted like it was inverted on the Y axis).
