| 5647.1 | Color depth of 3D30 vs 4D20 | BGSDEV::LANGONE | Thu Feb 06 1997 08:04 | 5 | |
The 3D30 is a pseudo color device that only supports 256 colors. The
PowerStorm 4D20 however does support that many colors being a
24plane/16meg card.

not on the HCL but the ZLXP-E series is - if you check you'll see that
the ZLXP-E1 supports only 256 colors.
from the Sales update on the 3D30:
The PowerStorm 3D30 graphics accelerator is a single-slot, PCI-based
module designed for 2-D and 8-bit 3-D wireframe applications. The
PowerStorm 3D30 is 8 bits per pixel, offering simultaneous display of
256 colors. It has special hardware functionality via a patented
dithering algorithm, which allows the display of virtual 24-bit images.
and for the 4d20:
The PowerStorm 4D20 graphics accelerator is also a single-slot,
PCI-based module designed for 3-D wireframe applications and
cost-sensitive users requiring 3-D solids modeling functionality. This
graphics accelerator offers up to 24 bits per pixel double buffered
(can display up to 16.7 million colors simultaneously), 4 overlay
planes, and a full 24-bit Z-buffer for 3-D depth cueing. The PowerStorm
4D20 also supports 1600x1200 resolution at 75 Hz to provide higher
quality resolution and larger screen sizes.
