I have a base model 5300, and its original grayscale display is passive, not active. Interestingly, the back of the display has a different style than the other 5300 models, with a horizontal line and two vertical lines in the center of the case as opposed to the two vertical lines on the outside of the case in the other models. It's also the only basic 5300 I've ever seen in person even though I've managed to accrue a stack of the cs and c variants in addition to a couple ce models.

I'm not 100%, but I'm pretty sure that, like the variable amount of soldered system RAM, installed VRAM for the internal display wasn't always the same between models: the base model 5300 likely had around 256k, whereas the midrange color models had 512k, and the 5300ce probably had between 512k and 1MB. As for the "N/A" or "1MB VRAM" figures quoted on sites like everymac.com or LEM, that's the VRAM on the optional external video card, not the internal display.

On another note, has anyone ever seen the 3.5" CDROM drive for these things in person? They were supposedly available but, like the LiIon batteries for these machines, nobody can find them. However, I'm pretty sure that the reason these drives are so rare is that nobody used 80cm discs, not that they were recalled due to a fire hazard. The only example of this drive I've ever seen was in Jeff Goldblum's 5300ce from Independence Day.
