How about backing store ? The R2 release supports color (at its normal lethargic pace) on Sun4/260C and Sun4/110C configurations. Adam de Boor has supplied MIT with backing store support that is machine independent - we use it on all Sun configurations. > > I also have a question about how the Sun server is implemented: > Does it use pixrect calls for all of the graphic operations ? > If not, where are all of the low level routines that write to the frame > buffer.

The fact that the server treats all Sun displays as memory, without using the hardware ROP support, is part of the reason why it is slow on color Suns. No pixrect code is used at all. For details, see the paper "Godzilla's Guide" that Adam & I wrote - it is in the R2 documentation. David.
