Yes, exactly. Thanks.
I re-assembled my Quadra 700 with 2MB of VRAM yesterday for Video
support testing.
  "re-assemble" means that I usually install Wonbat (Q650 Logic Board)
  in Q700 because it's faster and I didn't know the following.

Does someone have any information about 30-pin 32MB or 64MB SIMM?
I run Google and found a few 30-pin 64MB SIMM, but it's someting special
and it doesn't seem to work on Quadra 700.

Anyway, I put 6 x 256KB VRAM (total: 2MB) on Q700.
As Jon pointed, it shows the following on MacOS 7.5.5.

Video Memory 2MB    VRAM (6x256K):
 Resolution
  640 x 480      24-bit
  832 x 624      24-bit
1024 x 768      n/a-bit
1152 x 870      8-bit

On NetBSD-1.6.1, only 256 colours (8 bpp) depth setting in the Booter
works properly.
In Thousands or Millions of colours, console shows ugly, broken lines,
and also 'startx' fails with;

I remember "Known problems with this Xserver";

I don't understand this exactly, just I know that Q700 + ColorX has
some problem(s) in 16 bpp.

2MB of VRAM makes a difference from onBoard VRAM 512K (256 colors)
even though ColorX runs at 8 bpp. 8 bpp (256 colors) X is not enough for
graphic of course, but not so bad for text in twm.
(Windowmaker is my favorite, and it shows ugly icons within 8 bpp ..)
Quadra 700 with 69MB runs X not "quite slow", it's 25MHz, so so.

I tried "Futura II LX" (supported NuBus video card), but unfortunately
it goes down "uvm_fault, db> " on Q700. I don't remember any supported
NuBus video card better than Q700 onBoard Video.
(Other high-end NuBus video cards, such as Radius Thunder IV GX, are
not supported yet.)

Does anyone run Q700 ColorX with 16 bpp?

Yes, 4 x 16MB and 4MB onBoard, total 68MB.

dmesg:
Apple Macintosh Quadra 700  (68040)
cpu: delay factor 800
total memory = 69632 KB
avail memory = 60364 KB
using 896 buffers containing 3584 KB of memory

It's a good idea to inclease the size of RAM and VRAM.
