-
- There is no such thing (as far as I'm aware on the market) of a
- separate math coprocessor for the 68040. The 68040 has a built-in
- math coprocessor, albeit does not include transcendentals (in
- this respect, it is just keeping up with the RISC chips).
- However, what the first poster was talking about, is that Apple
- is probably going to use a low-cost version of the 68040,
- a chip which Motorola produces for all its customers, not just
- Apple, which drops the floating point part of the 68040. This is
- what Radius uses in their low-cost Rocket 25i.
-
- This version of the 68040 (called LC for low-cost, believe it or not),
- costs around $200-300 less than the full-blown 68040 (which is what
- Apple currently uses in the Quadras). Thus, for those people who do
- little floating point, they'll be able to buy a machine with 68040
- performance at a much lower entry point price.
