JP1 Remotes

I have a JP1 cable (6 pin), using old software (IR6.15 and KM8.35).
It has a JP1 connector, but not sure about the EEPROM (I bought it from jhuang on here, so hopefully he'll chime in). IF not, can I tell w/out opening it up?

Trying to configure my new-to-me URC8017.
Is it possible to program the FAV or HOME THEATER buttons? The HT button would be a good "turn everything on/off" button.

If so, how?

I have a cable, so it looks like I just bought the last one!

I'm possibly interested. I have a Panasonic Showstopper (ReplayTV). My latest JP1 remote is dying (Radio Shack). Any idea if this will work with it? No reason to replace the ReplayTV while it still works.
