- One card can only drive one monitor at a time. Even a SuperMac/RasterOps
- Big Huge Model can only drive one monitor. With the micron + adapter, you
- have the option of the external or the internal.
- It's kind of like a modem attatched to two lines. You can use either one, but
- I dare you to use them both at the same time.

- It fits in an SE/30 case with another card, so it's gotta be pretty small.
- I've never seen one though.
