Adding Video Memory

Your computer comes with 512KB of video memory. 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, 70ns. Additional video memory is useful for running graphics-intensive applications or for supporting resolutions up to 1280 x 1024 in 16 colors (interlaced) on your monitor. See Appendix A for a table identifying supported colors and resolutions for each amount of video memory.

For the memory to work properly, you must install one chip in each empty video RAM socket on the system board.

Note that your video memory sockets may not look exactly like the ones in the illustration. If you’re not sure how to install video memory chips, contact the EPSON Connection or ask for assistance.

1.Locate the video memory sockets on the main system board, shown on page 3-5.

2.If there is an option card in your way, remove it. See page 3-16 for instructions.

Caution

To avoid generating static electricity and damaging the memory chips, ground yourself by touching the metal surface on the inside of the computer’s back panel. Then remain as stationary as possible while you install them.

3.Remove the memory chips from their package and inspect

each one. The pins should point inward at slightly less than a 90° angle. If any of the pins are not in this position, use your fingers or small tweezers to gently align them with the other pins. Be careful; the pins are fragile and can break off easily.
