Still looking for VRAM for my LC575. The same SIMM is used in a variety of Macs around that age and before - basically all the LC range and the Quadras. My 575 is an ongoing project that has been halted by an analogue board problem (black screen on startup with a faint horizontal red line after awhile) and the yucky display caused by bad VRAM.
