Re: Apple II cassette drive.

Cables needed:

Two 2 conductor audio cables with 1/8" phono connectors on the ends.
You can do it with one, but you'll have to switch back and forth.

You DO NOT need dos3.3.  The tape load/save routines are right on your
ROM chips in the apple.  You can either turn on the apple and type LOAD
in caps, and then press PLAY on the tape player.  YOu'll hear a beep
that lets you know the apple is reading off the tape.  There is a short
audio 'header' on the tape which the apple II synchronizes to.  You'll
hear two beeps if the load was successful and your program will be in
memory.  You'll have to experiment with volume/tone levels on the
player.  When you get them right, hot glue them where they are (use a
50 cent player from the swap meet)  There are ROM routines to load and
save shape tables and Binary files to disk.  You have to type CALL -151
to get into the machine language monitor, and then type in the address
of the routines and type G (for go, otherwise known as RUN).   You'll
have to refer to an apple II reference manual for the ROM routines.

LOAD and SAVE work when you turn the apple II on.

I used the cassette ports for a project a while back.  I think they
work great.  A little slow.

Other things that worked off the cassette port:  Audio record and
playback (no extra hardware required!), a certain commercial hardware
item that I am making a webpage for, and what else?  I've seen the
files on an FTP site for sending files to a PC through the cassette
ports (I think.  It might have been the gameport)
