82C55A

Hello. I'm trying to find a replacement for an OKI MSM82C55A-2JVS.
I've samples some Intersil IS/CS82C55A parts but they reset with ports
to 1 (AFAICT). Has anyone substituted for the OKI part successfully
w/out a re-design? If so, which part? I'm basically looking for a
high speed 82C55 which reset to 0.

Thanks!
