I'm a few hours away from San Francisco, and I have an extra C128! When are you arriving, and how long are you staying?
This is just too good to be true! I'm arriving next Friday, the 24th and leave the 3rd next month. I'm going on a business trip so I'll be busy most of the day Monday to Friday, but I'll not be working the weekend, so I could definitely meet up somewhere then. I'll send a PM.
