RE: Asteroids Deluxe 12.096MHz xtal

I've also got a question about ordering crystals. I usually order my parts
from Mouser and in their catalog, most of the crystals have two choices:
series or 20pf. Which one should be used on Atari boards or does it really
matter?

Thanks,
-Chris

Digikey has them available (Digikey part number X031-ND, ECS part number
ECS-121-S-1)... but I'd hate to order an 84 cent piece to get that
section
of the board working (Digikey requires minimum $25.00 order)... only to
find
out other parts down the line need replacing also and having to order
those
as well. For diagnostics, I will simply use the 12.000 MHz then replace
when the board is deemed working. Thanks.
