The IA186EM/188EM is a form, fit, and function replacement for the original Advanced Micro

Devices

technology produces replacement ICs far more complex than "emulation" while ensuring they are

that even the "undocumented features" are duplicated.

This Advance Information Sheet contains preliminary information for the IA186EM/188EM. The

complete data sheet which documents all necessary engineering information about the

IA186EM/188EM including functional and I/O descriptions, electrical characteristics, and

applicable timing will be available when the device nears completion.
