ULSI US83C87 DX/DLC, 40 MHz


ULSI Advanced Math Coprocessor DX/DLC 40MHz US83C87 10501 (R)(C)1990 9401A3C	D0092 PHILIPPINES

The DX/DLC is a slightly enhanced version of the original ULSI 83C87 with increased standards compatibility, but still not 100% IEEE conform. Some transcendental functions have also been sped up.
