In the June 1989 issue of BYTE Magazine, Bradley Dyck Kliewer wrote an
article entitled "Debunking 16-bit VGA.  In that article he tested six
16-bit VGA adaptors for the AT bus.  He states that of all the boards
tested, none had 16-bit latch registers.  His benchmark tests for
copying a block of pixels to the entire screen byte by byte gave results
in the 10 to 20 second range (for video mode 16, which I assume is
1024x768x16 colors?).  I am not convinced that level of performance
would cut it for an X-terminal application.  Mr. Kliewer suggests using
graphics coprocessor boards; are cheaper ones coming?
