Nope, not in my machine :) UW SCSI is as far as I go...

Does this mean you would use i2c function calls, or twiddle bits on the
parallel port to simulate the i2c activity?

This could be the parallel port adapter I saw the driver for. If you can
dig up the docs for this, that would be great

Thanks
