I realize that softFPU emulation is fairly mature, but what I'd like to do is produce tests against silicon across three generations (8087, 287 and 387) so we capture any hardware differences and edge cases. Also operational quirks in addition to arithmetic results.

These tests would also capture all bus cycles, so people can study how the FPU handshaking worked across generations.

I should probably track down that test suite and see if i can translate it directly to SSTs
