Video
The onboard video system is essentially a PDS frame buffer with 512k onboard 80ns memory and two slots for 256k 68-pin VRAM SIMMs. It supports 1, 2, 4, 8, and 16-bit color modes and on-the-fly resolution switching.

2 x 512k will function identically to 2 x 256k.
When used with an OrangePC 290, built-in video is more responsive than SuperMac Spectrum Power 1152 (though it appears faster in QuickDraw benchmarks.) Other cards have not been tested.
