[QuadList] Another Weekend Quiz 04/01/11

[Don Norwood]

It's not easy finding things to challenge you guys, but here's my attempt for this week.  The manufacturer is probably obvious, so I'll require a 3-part answer to fully qualify as a win.....

    1)  Manufacturer
    2)  Model
    3)  Switch function
