There has been considerable discussion already on the pros & cons of the
approach used by Digital on the DECStation 3100 of using the cpu for all
graphics tasks (basically the idea is that the cpu is so fast that graphics
operations are limited by memory bandwidth, so graphics engines will not
improve graphics performance, apologies to DEC if I am oversimplifing)).
  Now I see there is another example.  The Data General Maverick 88000 based
workstation uses an NEC 72120 (whatever that is) for mono and a custom
gate array (whatever_that_is**2) for color.  Any DG engineers out there who
would like to discuss why they chose to do so?
