RE: [N8VEM-S100:4992] PCB Via Counts

They seem to classify  less than 500 or greater.  It does not seem to make a
big difference in price as far as I can tell (at least with PCBCart).    The
number 1 factor, is the number of boards.  There is a "setup fee" fee of
$70-$80 for each new board. After that it's a board cost.  Just place the
(large)  order for the 80386 + RAM boards, total ~100 boards, works out to
be ~$13/board.

Are there any guidelines for acceptable number of via's on an S-100 PCB? How
do quantity factor into manufacturing?
I'm guessing fewer number means less cost and possibly shorter overall trace

Autorouter starts to slow down and eliminate less and less.
Doesn't seem like it's worth it to continue to run autorouter to reduce via
with results like 1 or 2 a day.
