Panasonic CF-VEBC11U DESKTOP PORT REPLICATOR WITH DVD MULTI DRIVE FOR CF-C1

Additional ports, and combo optical drive. No issues.

Work just Great.....

I have 8 Toughbook C1's presently with about 20 more on the way.It would be much much more difficult to work on these machines without this dock.The description here is pretty much useless, so allow me to spell out the features:Includes a DVD-RW driveGives you a bunch of I/O options on the back:RJ-45 ethernet jackeSATA port4x USB portsHDMI-outVGA-outI'll take some photos and add them to the product description.This dock is a bit pricey, but it goes with a $2.5k laptop  CF-C1,12.1INCH Wxga MULTI-TOUCH,250GB , so I guess it isn't that expensive in the grand scheme of things.Simply put: it just works. I never have had a problem docking or undocking (no lockups or blue screens, etc).One last note: the dock does NOT include a power supply. You'll either have to use the one that came with your laptop or buy a new one.
