Hello CobraJunkie,
First off, welcome to the SAAC Forum. A signature first name would be nice unless you prefer to be called CobraJunkie.
Anyway, I just so happened to have my older 97 registry sitting here. Keep in mind there are two newer registries on CSX3000 series cobras (one very current as in 2019) but the info on CSX3270 is fairly well documented unless it has been sold again.
I'd recommend purchasing the latest edition, but none the less here's the info you are seeking.
Cheers
