You can do a lot of damage with a Dremel, the big problem
being that 
it's hand-held.  This is one case where I might be tempted
to use a 
jeweler's frame saw and use as many blades (they're very
cheap) as 
needed to get the job done.  Alternatively, a small carbide
bit in a 
table-mounted router would do the job in a jiffy.

Personally, I'd just find out if the IC was available in
PLCC.

Cheers,
Chuck

Got one of those,  but no blades at the present time,  I
oughta do something 
about that one of these days...

I might get a router-type bit for the dremel,  too.

The whole point was that I already have four of these chips
sitting around.  
If that weren't the case I wouldn't be tempted to explore an
otherwise 
obscure processor like that.
