- Unless you damaged the motherboard in the process of hedgehog extraction,
- it should work very well, chugging along at 50 MHz with beautifully clean
- signal waveforms. Connect an oscilloscope and enjoy while you compute.

- odd bit of blue smoke from some parts of the random logic on the motherboard.
- I would be very surprised if you could actually get that to work for more than
- a few hours - if at all.
