I haven't yet tried to salvage any surface-mount chips,  yet,  though I do 
have a board here with a few transistors that are tempting me.

8 ns?!  That's _fast_.  What if you don't mind my asking are you doing that 
needs those kinds of speeds?  I'm used to thinking of access times in numbers 
that are three digits long.  :-)   Some cache I snagged out of a defunct 486 
board is about the fastest I've managed to salvage yet,  and it oughta really 
do just fine with a z80 or something,  no wait states there!
