Can anyone point me to a source (or sources) that stock Atmega 
chips?  I need 25 - 50 atmega8515-16 in 40 pin DIP, either standard 
or industrial temp rating. My usual sources (digikey, mouser, 
newark, etc.) don't have any and no word when they will be coming in.

I've tried findchips.com and several other distributors also, but no 
joy.

Help! Got deadlines to meet and no chips. Surface mount is out and 
so is changing chips (board design is set in stone at this point).

Thanks,

Chuck
