San Francisco Vacation

[vts1134]

I'm going to be going on a trip to San Francisco this June and was wondering if there are any antique television related sites that people might recommend seeing. As luck would have it I'll be staying in Telegraph Hill a 20 minute walk to the spot of Philo Farnsworth's laboratory. From what I can figure out it's not a museum or anything, but it will be cool to see it non the less. Does any one have any other suggestions for site seeing?
