Want a OrangePC 660

I have an OrangePC 550 for sale. It comes with a 450 MHz AMD K6-2+ processor (runs at 400 MHz) and a 128 MB RAM stick. The OrangePC 660 will run at 450 with the K6-3, or at 550 MHz with the K6-2, but it is not compatible with the K6-2+ or the K6-3+ processors. In addition, the 550 has physical LPT, COM, audio and game ports, but not the 660.
