In his Hardware Review in the Jan 1989 BYTE Magazine entitled "Pixels on
the March", Bradley Dyck Kliewer reviewed the 8514/A coprocessor board.
In its highest resolution mode (1024x780 pixels x 16 colors) the 8514
sends an interlaced signal to the display.  It has been stated several
time in this newsgroup that 1024x768 interlaced is almost
indistinguishable from 800x600 pixel SVGA.  This is, of course, just
the sort of technical problem that the clone makers delight in
rectifying, so I guess maybe I'll be happy when this board becomes a
universal standard.  What I really want to do is put together a 1024x
768x16 color noninterlaced X-terminal, based on a PC, that can update
the entire screen in less than 2 seconds.  I think that a SVGA adapter
with real 16-bit latch registers should be capable of something in the
range of 5 to 10 seconds.
