The Weitek WTL 1167 is found on Compaq's Weitek Coprocessor Board. The
WTL 1167 is a set of three chips used as a replacement for the Intel
80387. Benchmarks in the 1988 March BYTE, show the WTL 1167 with a 7
percent to 68 percent speed increase over the 80387 on processing of
double-precision numbers. ("Real-World" speed increase is more like 30
percent.) Compaq's Weitek Coprocessor Board was designed with an 80387
socket.

Microsoft only has Math Coprocessor support for Intel chips. If you
have the WTL 1167 on a Compaq Weitek Coprocessor Board, you also must
have an 80387 to use our Math Coprocessor Library. Without the 80387
you will have to use our Emulator or Alternate Math Libraries, or link
with a third-party library.
