I believe there are two color 5300 logic boards ... one supports a TFT with 640x480 (5300c), or less, while the other supports 800x600 (5300ce).
Er, sorta. There's at least 3 different 5300 motherboards. One has 8MB of RAM and 512kB of VRAM, one has 8MB of RAM and 1MB of VRAM, and one has 16MB of RAM and 1MB of VRAM (this one is usually 117MHz). That means that there are three different boards capable of displaying color, one of which can only do 256 colors at 640x480 (16bit at 640x400). The other two can both do thousands (16bit) color at either 640x480 or 800x600, depending on which screen is installed.
There are VRAM chips on both sides of the logic board, and the 5300ce has all locations stuffed.
As a matter of fact, there are places on the logic board for four small RAM chips and one large RAM chip on the bottom and also on top, and the various models of machines have different combinations of small and large chips,
Right. There are pads for 8MB of RAM on top, 8MB on the bottom and 512kB of VRAM on top, 512kB of VRAM on the bottom. They usually get filled from the bottom up.
Peace, Drew
