This is a lovely chip, agreed. Now, if only the price would come down
to where one could afford to use it in a moderately priced system....
Our hardware guys had to reject it right away becuase of its' high cost,
and because the AT&T rep didn't see any prospects of it coming down at all.
We were facing having this part be the most expensive chip in the system,
since the 68020 CPU and 68851 MMU are clearly coming down quickly.

Sigh.
