All you need is a socket that supports the 32381 and the 32580 Weitek interface
chip (yes, the two are compatible, and one socket can support both -- here's 1
boo-boo we DIDN'T make). Once you have that socket, you can leave it empty, or
plug a 32381 in, or -- for real FPU power -- plug in a 32580/Weitek pair.
