ELKCO has a *NEW* 82S87-20 for $85.  This is made by Cyrix and I figure that
it is a product that has just come out.  They might make a -16, but it is
not listed in the ad.

Besides I thought that '287 chips ran at 2/3 the speed of the '286 that
was connected.  If this is true then a 12Mhz would do just fine.  Of
course this is probably board dependent.

BTW, ELKCO's number is 1-800-24-ELKCO  (243-5526).  If you need anything
more than the number look for my post on street prices for '387s.

owls eat mice, and thus make a certain number of cats unnecessary, which
is always a plus.  Jeff Duntemann, Dr. Dobb's June '91
