IBM has gone to their own proprietary gate array chip with the
introduction of their Video Graphics Array (VGA) - standard on
all PS/2 systems (Built into mother board). The output of the VGA
is analog RGB. Sixteen colors may be displayed at a resolution
of 640 X 480. 256 may be displayed at a resolution of 320 by 200.
The palette is 256,000.

IBM has also announced two proprietary graphics coprocessors, the 8514
and the 8514/A. The 8514/A with optional memory will be capable
of displaying 1024 X 768 X 8.

It will be interesting to see some comparisons between the PS/2 with
the 8514A graphics coprocessor and Quadrams QuadHPG Series I (Intel 82786 based)
graphics card which also displays 256 colors but at 640 X 480. Although
Quadram has promised higher resolutions in their HPG Series II and III
cards due out later this year/next year.

Besides resolution is only half the story. I am interested in
bit planes. I am still looking for a commitment from ATT and
Number 9 (or anybody else for that matter) to produce one of 
their 32 bit plane graphics cards for the PS/2 system,  or better 
yet the MAC II.
