Quoted from Collin:Anyone still at the show happen to have a 6821 PIA? Please shoot me a PM if you do.
I'm not there but somebody needed one in Texas - and they found one on an old williams sound board. A little solder-sucking to free it and they popped in where needed. Point is if anyone is selling "junk" boards, give them a quick look-through for the PIA.
