There are chips that convert between serial and parallel ATA; one of those
could perhaps be used. I'm more used to applying them for attaching a serial
ATA controller to a parallel ATA drive, but possibly they might work in the
other direction as well. Not clear if they are still common products, given
that parallel ATA is pretty old, but they may still be available.
