Pro-96: Is the Pro-96 Updatable?

Almost ten years ago (!!) I bought a Radio Shack Pro-96 scanner. It's been a great scanner, still runs a well as the day I pulled it out of the box. However, I have never updated the radio's software. I have read that an update in 2008 unlocked 700 Mhz for rebanded trunked systems. Is it possible to:

1) still find the programming cable, and

2) even if I find it, is the update still available from the RS website, or archived someplace at least?

Thanks!
