DVE Board Jumpers and Modules

The DVE board has several jumpers and plug-in modules. Some
modules are small printed circuit boards that install parallel to the
primary board, and attach with standoffs and Phillips screws. Others
are SIMMs (Single In-Line Memory Modules), and plug in
perpendicular to the primary board.
See the instruction sheet in the front of this manual for details on using
the insertion/extraction tool for removing and installing circuit boards.
When removing and installing the plug-in modules, always place the
circuit board on an antistatic flat, smooth surface. This provides support
to counter the pressure used to push the modules into their sockets and
prevents the board from flexing and possibly causing damage.
The Address Generator module plugs into two sockets: J8F1 (120-pin)
and J4D1 (160-pin). It provides the main transform address generation,
warp address generation, and the light source and texture functions.
There are three sockets for the DSP (Digital Signal Processor) circuitry
memory SIMMs:
There are eight Filter Coefficient #1 SIMMs. They are identical, although
some are used for horizontal processing and some for vertical:
4-12
System Overview
NOTE: Always observe proper antistatic procedures when
handling circuit boards and electronic components.
Failing to do so can lead to permanent damage.
NOTE: Use extra care when installing and removing the
Address Generator board from the DVE board, and also
carefully support the back of the DVE board to prevent it
from flexing.
