Removing An Option Card; Adding Video Memory - Epson ActionTower 3000 Computer User Manual

Removing an Option Card

You may need to remove an option card installed in your
computer to access components on the main system board-to
change a jumper setting, for example. You may also want to
remove a card if you no longer need it. Refer to the illustration
on page 3-17 as you follow these steps:
1. Remove the retaining screw securing the option card to the
computer. Then pull the card straight out of the slot.
2. Set the card aside with the component side facing up.
3. If you are not installing another option card in the empty slot,
replace the option slot cover and retaining screw.

Adding Video Memory

Your computer comes with 512KB or 1MB of video memory. If
you have 512KB, you can increase your video memory to 1MB
by installing four video DRAM DIP (Dual Inline Package)
chips. The chips must be 20-pin, 256KB chips that operate at a
70ns access speed. For the memory to work properly, you must
install one chip in each empty video RAM socket on the system
board.
Additional video memory is useful for running graphics-
intensive applications or for supporting video resolutions up to
1280 x 1024 in 16 colors. See Appendix A for information on
supported colors and resolutions for each amount of video
memory.
