The 83D87 is indeed very fast on transcendental functions, and at
least as fast on the other stuff. Also low power (aka low heat, better
reliability).
| How to get it:
I get mine through ELKCO in Boston MA USA (800-24ELKCO). They have the
83D87 in stock, I believe they have the 486 but haven't asked.
How to use it:
The 486DLC requires enabling of the cache to run full speed. As I
recall there's a DOS program to do it, and that's one way to get it
going until someone diddles the kernel.
