STAR SYSTEM VIDEO EMULATION SRAM
When the ZT 8907 is used in a STAR SYSTEM and sharing a video card with other
CPUs, a 128 Kbyte SRAM module must be installed in socket U17. Perform the steps
below.
1. Install a 128 Kbyte SRAM module into socket U17.
2. Remove all jumpers from W2 to enable the video RAM region when the system
re-boots.
3. To conserve battery life, always battery-back this SRAM by making sure jumper
W4A is installed; installing W4B may increase battery drain when SRAM is installed.
