Wow! I had finally found a post on DDB (search for "Cheer" and "roadmap") which outlined the steps and now this pops up.

I must be living right!
100Tbps, thanks! When I've finished my upgrade, I will have to spend some time checking out the archiver (sp?) which held a copy of the page. I had hoped that something like that was out there but had no luck in finding it. (I've become overly dependent on Google.) In the mean time, I saved a copy of this for my reference. (Don't ask how many old copies of tivo hacking stuff I've save over the past few years!)
Gunnyman, don't sell your work short even if it does have a gray hair or two! While I am appreciative of the simplicity of the Zipper, the TiVo I want to upgrade is my 2nd so I am prone to "get my hands dirty" and make it a 're-learning' experience and the Unguide was/is awesome for that purpose.
