I've been puzzled by something for a couple of weeks now, so I
thought I'd post for a response.
Here's the setup:

Mac #1 (home):
	SE/30, sys 6.0.5, RasterOps ColorBoard264, 8Megs memory,
	40Meg internal HD, 105Meg LaCie external HD

Mac #2 (work):
	IIsi, sys 6.0.7, built-in video w/AppleColor 13" RGB, 5Megs
	memory, 80Meg internal HD

Reading my one free issue of MacUser (June '91), I found out how to
switch the StartupScreen from the internal to the external monitor.
On the IIsi, a 256 colour StartupScreen flashes to the screen quickly
in one fell swoop; however on my SE/30, the same picture paints more
slowly (1.5 - 2 seconds) from top to bottom.
Why the difference?  The RasterOps board (especially in 8-bit mode)
has out-performed all other 8-bit displays I've seen on Mac II's,
IIcx's, IIx's, _and_ IIsi's except for the display of colour startup
images on my IIsi at work.
I thought the dedicated video card would have beaten virtually any
built-in video (which it does in normal operation), but now I'm not so
sure.
So, can anyone answer why the IIsi's StartupScreen displays so much
quicker than the same image on a colourized SE/30?  4MHz can't make
that much difference!
