    Re: i have an old PCM

    I have like 10 of them, but I recently killed 2 of them pulling the chips and then trying something dumb. Holding the chip down on the board and reflashing the PCM with the other hand. What was I thinking? Not once but twice

    Re: i have an old PCM

    hey AJ. is there a way this one might work if you flash a tune on it or what not?
    I dont know to what extent this old one is ruined but it was giving me alot of :loss of data" codes when it went.
    could it be it just needed to be re flashed?
    what can i do with it pay you to make a preformance PCM out of it ?
