Question: Have all of the original actors on Bonanza passed away now? — Linda, Omaha, Neb.

Televisionary: OK, let's make it a Bonanza bonanza. The answer is not quite. Lorne Greene (Ben Cartwright), Michael Landon (Little Joe), Dan Blocker (Hoss) and Victor Sen Yung (Hop Sing) have, but 76-year-old Pernell Roberts (Adam) is still with us.
