1227730

[Jon Fedock]

    What I have been doing is to pry up on the eprom lightly with a
screwdriver, and push each of the header pins down one by one (they have
*TINY* amounts of solder holding them that breaks away relatively easily).
Then pull all of the header pins up slightly (for easier access to soldering
iron) and bend all of the pins on the socket out to make the ends match.
Next solder all of the ends together (steady hand here!). Then push the
socket down till all of the header pins are back "home," and then check all
connections with a meter (also checking for shorts). I usually put epoxy in
the middle to make sure vibration/fatigue isn't a factor. This system has
worked well for 5 cal paks, and there is still room to put the cover back on
the ECM. Total cost is $0.99 at radio shack for a socket, and a little
solder. Maybe my description is good enough. Good Luck
