In defense of the 386i, remember that on a color system it ALWAYS uses color for SunView. On a 3/60 or 3/110 the system will use the overlay plane for most windows so the system is refreshing only one bit plane, not eight. The 386i has only 8 planes (no overlay plane) so all windows are maintained to a depth of 8. This is the price we pay for color. We have one monochrome 386i system and I feel that SunView works about as well on it as it does on our 3/60. Having said all that, I tend to agree that the 386i model 250 seems slower than I would have thought it would be, especially since Sun advertises this as a 5 MIP machine. - Glenn Roberts, MITRE gfr%wolfgang@gateway.mitre.org
