IIe ROM code modifications - exchange tape drivers for ???

["Craig Bower" <to.email.me@post.a.request.message>]

Hi All,

I'm trying to find out the start and end locations of any and all cassette 
tape routines built into the //e ROM code.

Reason?  I want to reprogram these areas on my Applewin emulator to do 
something else.  As it's extremely unlikely I'll ever hook a cassette tape 
player to my PC.

Any ideas?

Later,
Craig
