I received this with a recent conquest of an Apple 15" Display. It also came with an Apple 205W Power Adapter P/N M5849. They appear physically compatible with each other, but the power adapter seems a bit over the top for such a small device (its over twice as big and easily 6 times the weight of the converter!!). The only things Ive found out about it are that the P/S was used with the G4 Cube, and that the output seems to be at the maximum the VGA converter can handle. I found the specs on the manufacturers website http://www.gefen.com/kvm/dproduct.jsp?prod_id=1301

ADC Bandwidth: 165 MHz

VGA Bandwidth: 350 MHz

Input Video Signal: 1.2 Volts p-p

Input DDC Signal: 5 Volts p-p (TTL)

ADC Connector: 35 pin female

VGA Connector: HD-15 Male

Power Consumption: 208 Watts (max.)

Power Supply: 24-28VDC 60W

Dimensions: 2.75"W x 1"H x 4.5"D

Any insight? Thanks!!!
