   supports both the original Losmandy motors, Maxom Motors, and the new
   high torque Losmandy motors
* GPS-compatible with optional receiver
* Stand-alone system. No PC required!
* Ethernet 10/100 with full DHCP/Static IP functionality permits operation

   4Gbyte max, SD and SDHC types supported)
* Two Serial ports with +/-50V ground loop isolation
   (com 2 is used for Graphics Hand Controller - set it to 57600 baud)
* Two USB ports; (USB-B, marked USB is functional now. USB-A for future support.
   USB-B has Windows driver producing a Virtual COM to PC, for connection by
   ASCOM or planetarium program.

* With the new L5.1 Firmware and the new Servo Firmware, the Gemini-2 will be
able to talk to the servo chips. The servo firmware is still work in progress,
but it closes the loop. The servo lags and PWM duty cycles are now available
in real-time over the serial interface and a new Servo web page. Also,
L5.1 supports Alt/Az mounts, but there's still some work to be done. (This is only
available to the Beta group at this time for testing.)
