Cheap SCSI cards can be had for $30US and if you really insist on using a laptop, you can find USB to SCSI adapters for around $60US.  Something we need to keep in mind here.  Debugging a PCI interface is not an "average hobbyist" task.  Needing somewhat "specialized" hardware to accomplish it is not unrealistic.

If thinking this way then USB-to-IDE would be cheaper (<$10), enough
fast (25MB/s +) and probably ATA is also simpler to implement than SCSI.

I'd rather choose IDE, its quite universal - having PATA directly and
you get also USB / FW / SATA with commercially available converters.
