				Mac LC			Mac IIsi
Macintosh 12" RGB Display	x (256 colors)		x (256+?)
Macintosh 12" Mono Display	x (16 grays)		x (256 grays)
Macintosh 13" RGB Display	x (16 colors)		x (256)
Macintosh Full Page Display				x (4 grays)
Some VGA Monitors		x (16 colors)

Note: There is an optional 512k VRAM SIMM for the Mac LC that will
boost shades available to 32,000 on the 12" RGB display, and to 256 on
all others supported.

Note 2: The Mac LC uses independent VRAM for video, where the IIsi
cycle-swaps memory from the CPU, resulting in severe performance
degradation on the IIsi in 8-bit mode.

Note 3: With optional NuBus card, the IIsi can use virtually any
monitor, with the addition of the appropriate card.  The LC needs
cards desgened for specifically for it.

	I have heard of none.

	Be certain to note certain limitations inherent in the LC:

	o No external floppy port.
	o No Apple-supported provision for an FPU or PMMU
	o Unique expansion slot ('020 PDS).
