Video Memory (SGRAM)
The manual Setting Up Your Power Macintosh and the Technical Information booklet state
that your computer only has 2 MB of video memory built into the computer’s main logic board
and that you can add video memory by installing a Small Outline (SO) Dual Inline Memory
Module (DIMM) in a slot on the logic board. However, if your computer came with
6 MB of video memory, a 4 MB SO-DIMM has already been installed in the expansion slot on
the logic board. You will not be able to add any more video memory.
