     The IBM Professional Graphics Adaptor has been discontinued by IBM.
The unit was too expensive to achieve any significant market share,
and little software supports it.  Since it contains a CGA emulator, though,
MS-DOS can support it in text mode, although the resolution is reduced from
the excellent PGA resolution to the terrible CDA resolution.

     AutoCAD supports the PGA.  So do Dr. Halo and packages based on
that library.  But few other packages do; the Turbo family, for example, do
not.  EGA and VGA are now the de-facto standards.

     Matrox makes some very nice boards that emulate the PGA, and include
some other capabilities.  Their most advanced board has a full solid modeller,
including a Z-buffer.
