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.
