That's odd, we must have different R6.3s.  At public-patch-1, I find
that "man Xsun24" produces a page that says, in part,

       frame buffer.  Xsun24 supports the  cgeight  24-bit  color
       frame buffer in addition to the 8-bit color and monochrome
       frame buffers that Xsun supports.

It depends on the hardware.  If - to use the X terms - it's TrueColor,
you don't, in functional terms, have a colormap.  If it's DirectColor,
you have 768 bytes of colormap (three 256-element maps, one per
primary).

1280x1024?  Most Sun framebuffers - at least the ones I've seen - max
out at 1152x900.  I've got a bwtwo that supports 1600x1280, and I hear
colour exists at that resolution but have never seen it personally (the
monitor would surely be mucho $$$, if nothing else).  I've seen a
framebuffer run at 1024x768, and have seen indications that some do
1024x1024.  I don't think I've ever seen or heard of a Sun framebuffer
running 1280x1024, though.
