ACP is in Santa Ana. IT is at 1310 E Edinger Ave, Santa Ana, CA
It is on the last Sunday of the odd months, Jan, Mar, May, July, Sept, Nov.
There are several computer stores and surplus dealers in the complex and other vendors that come from all over.
My opinion is this can be a hit or a miss event. It's not until you get there and find that gem that you will know if it was worth going to.
It starts about 7AM, but vendors arrive well before that, if you want to be the early bird... And ends about 1PM. but some vendors pack up a little earlier than that.
