I originally thought so too, but my 750 tech reference lists the pins on 
the connector (but not the AMP part number of the connector, dammit!) and 
the HD lines are _not_ on there. The only lines labeled as HD signals are 
-PDIAG, -HDCS1 and HD7. (Passed Diagnostics, Chip Select 1 and 
[strangely] data line 7.) There's a HDCS0 signal there too, which is 
(mistakenly, I think) labeled as video-related.

What does it do, convert the D connector to a standard 40 pin cable and a 
power socket?
