One of the Nuts and Volts Columns shows a set of subroutines that implements I2C for a BS2. I don't have the specific issue number handy, but you could look through the first 2 or 3 volumes for it.

Ive been looking at a couple of them, but i can't get my Acks together im trying to simplify it. what is a functional equivalent to a 12COUT and I2CIN commands

Like Mike said there is no direct equivalent, you will need to write your own, or find the article (N&V vol3 column #79) and it will tell you how to 'bit bang' it. Good luck.

There are a couple I²C columns in Volume 3. Here is a link to the volume index.
