Hogwash.  My beard has hardly any grey in it, and I have worked on
systems where every board and every peripheral came with a reasonably
thick manual.  These manuals used to have chapter titles like "theory
of operation" and "programming model".  Sometimes they had complete
schematics, more often just very good block diagrams.  Sample code too.

In the PC market you get a little bifold pamplet that tells you how
to take the lid off your computer without sticking any appendages
in the fan.  Grrrr.

I've done that once for a serial board (though I do hold copyright on the
design files) and it works OK.  My serial board comes with schematics
and PAL equations, and is available as a kit or assembled.  The netlist
and Orcad files are available if somebody wants to customize it.

I think it would be very difficult to compete with the mass-produced
VGA cards.  If I was going to build a video card I would either shoot
for radical simplicty or build something that you could run the whole
X server on.

The idea makes sense technically, but not economically in my opinion.
