Might be,  it's still loading...

I've been acting like an "information sponge" lately (thanks to my brother for 
that phrase) in terms of trying to accumulate as much info as I can get for 
the parts I've been accumulating over the years.  Getting a nice collection 
of datasheets,  too,  though I generally tend to favor more generic 
"jellybean" parts rather than some of the more specialized stuff that some of 
you guys are into.  Still,  if there's something that somebody needs data on, 
drop me an email and if I have it I'll pass it along.

Right now I'm looking for full data on things like MPQ2907 and similar -- what 
I've got seems to only list surface-mount parts,  and I have some in standard 
DIP.  I haven't hit Motorola's site yet,  though,  to see if they have 'em.

On another thread,  where people were talking about running stuff mostly at 5 
volts and needing a 2.5V reference,  there's a chip for that,  too -- the 
LM336,  which it seems I have a few of.  This part was also once available at 
Radio Shack,  but probably isn't any more.
