cpab,thanks for your reply.I'm not too bothered as it's a freebie,but I was checking it out before modding it.
Just turned it on and noted and photographed the settings.
My original Tivo,which I modded,died after about 2 weeks and I have no idea why.
I now have 2 more units I found online and just want one working unit for myself.
As I have discovered,it's pot luck what you get when obtaining old units when the owner doesn't know much about them.
The other one I picked up has a MAK and the latest firmware version.
