- Not really; it's true that it takes longer to draw when you
- draw into a lot of colors on the screen, but if you set the
- screen back to the depth it was before; you get the same
- speed you had before.
-
- You get the option to use more colors at a slower pace.
-
- With a 512k VRAM you get 256 colors on a 640x480 display (13" Apple RGB), or a
- zillion (<2 million) colors on a 512x384 display (12" Apple RGB). So you in
- fact do need this SIMM for 256 colors on a 640x480. The 256k VRAM only gets
- you 256 colors on a 512x384 display.
-
- You don't get zillions of colors; you get 32768 of 'em (15bit)
- The LC internal video cannot produce 24bit color (millions)
- However, QuickTimes native format is 15bit color, so the LC is
- actually not too bad as a QuickTime player - especially if you
- add a 040 card...
