I've exhibited at VCF West many times, you get part of a table or more depending on your exhibit, its a good time/place to show off your stuff and share your excitement of it.

Since it is mainly just enthusiasts, and limited to "vintage" (see event exhibitor info for the definition) it is a great place to reminisce and find some old hardware/software/media as well.

Here's some pics I took from when I attended (2002-2006) Later ones probably have the same vibe, and as it has grown in popularity you may see more tech luminaries attend/present.

The parking lot is full of vans and trucks, and some beleaguered sedans and stationwagons. There's tons of hardware, literally.

There are vendors that sell some stuff and there is a place where people drop off unwanted vintage equipment that you can take home for free.

Absolutely heavy on the hardware. Lots of micros, obviously, but there are always a few minis (PDP-8/PDP-11/HP 1000/etc), Unix workstations and odd stuff. This year there is even an IBM Midrange display (System/34, /36, AS/400).

Appropriate vendors are welcome and loads of stuff changes hands.
