i originally thought that the 6100 shared its ram for vram

but here is a link anyway to a 512k vram stick (shows its for LC, P475, P575, 8100, power book duo 210 and 230, and a few others)

It is where i bought my vram for my P475 (that exact same link) and the sodimm vram upgrade for my Beige G3 and could not be happier.

I always look at memory on their site if i cant find anything elsewhere.

You can even find the same 128mb stick of ram that works in my P475 from them.

BTW nice score
