<div class="moz-cite-prefix">Mmm - saw that one. Perhaps I'm being
dense, but how exactly do we think it works? It looks like just a
lever which applies pressure to the side of the socket, which we
have already agreed is risky. Phil's 3M tool has the advantage of
moving the fulcrum down to the bottom and pushing down on the
socket instead.</div>

<div>Yep, that would be better (as would pretty much
anything). Initial search does not throw up a source, but
it is like searching for a needle in a haystack made of
those wretched diamond things.<br>

If you pry with screwdrivers too much, these

"vintage".<br>

+1 to that, although for "can" read "almost

I have had no joy with those at all. There
seems to be only one design available - tiny
hooks which are drawn upwards as you squeeze
inwards on the diamond-shaped handle. I find
that what happens is: nothing...squeeze
harder...nothing...squeeze harder...hooks rip
a chunk out of the bottom of the PLCC, leap
out and score a nice deep scratch across the
top of the IC for good measure.<br>
<br>
I've got a faulty Lexicon PCM80 here where I
would really like to try changing the main
CPU, but it is a 68-pin socketed PLCC and I
can't get it out. I've tried, and the results
were as described above! As far as I can see,
you just need to treat socketed PLCCs as if
they are soldered in, and desolder the socket
with the IC still in it.<br>
<br>
I bloody hate PLCCs...<br>
