A USB MIDI interface would be a good way to hook up to a laptop
computer.  If you have a laptop Pentium or better, which does not have
a USB port, then install a USB plug-in PCI (PCMCIA) card in your
laptop.  This is a standard laptop card with a USB port.  Tiger Direct
lists them in their catalog, though I imagine that one could be found
quit readily from many sources.  Hope this helps.
