[Coco] Coco Cassette interface help

[RETRO Innovations]

I am trying to interface an Atmel AVR with the Coco cassette port, and 
before I get too far into the design, I am wondering if there are any 
existing Coco to uC via Cassette Port projects out there I can borrow 
ideas from?

Looking at the scope, it looks like I need to amplify the signals from 
1.2ish V before I can do much, and thought I'd see if tehre is existing 
circuits out there to use.
