Data in -- Data out --

I still say that sounds like the C64 casette port ( other than the
motor sensor.. which is easly fooled )

You could store, and retrieve, as much data from a tape, as the
physical formated size of the tape.
(kinda sound like a USB flash drive to me still )

I still think, there has to be away to use that port with a USB drive,
and create a mass storage device there. The "slowness" of the casette
recorder, had much to do with the physical speed of the tape ?? and
maybe the port itself... Im not sure... but from what I read and
assume to be true, the tape stored binary data.

I could imagine that the C64 could be "fooled" into thinking it had a
1 GIG datasette attached, easier than a IDE hard-drive (but thats just
a dream)

Easier to feel it into thinking its talking to a 1541 than that its
talking to a Datasette ... with the Datasette, it is controlling the
device directly, with the 1541, as with any IEC device, it thinks it
is sending messages down an interface to a microprocessor on the other
side of the daisychain.

So if you are taking over the datasette port, you have to control it
at a higher level ... though it does free up substantial code space
for operating the Datasette drive.

Actually, come to think of it:

A1: GND
B2: +5V
C3: Motor (Master to Device)
D4: Cassette Read (Input from Device)
E5: Cassette Write (Output to Device)
F6: Sense (Master to Device)

That would support a single Serial Protocol Interface device:

C3: Motor (Serial Clock)
D4: Cassette Read (Master In Device Out)
E5: Cassette Write (Master Out Device In))
F6: Sense (Select)

You wouldn't even need to change the start up code setting the I/O
direction.

And there would be no concern with interfering with a 9600bps serial
port on the User Port, so if its pure bit bang, the only interfacing
required would a TTL / Low power line driver.

Ideally, you'd want the USB part to be a USB-2-Go part, so that the
C64 could both use is to access peripherals and use it to allow the PC
to access it as a peripheral.
