Disk controller unit (IWM) <==> D-19 pin connector <==> uC (Arduino)

IWM provide synchronous and asynchronous modes.

IMW Pinouts Cable Pinouts
8               19        WRDATA  The serial data output <---->  In line uC
22              18        RDDATA  Serial data input line <---->  Out line uC
21              10        WRPROT  Write-protect input    <---->  Out line uC
Power  <---> +-Vcc
GND    <---> GND

You think that is it possible to do ?
What do you think about ?

Thanks

Ric.
