Repurpose laptop to household touch screen calendar?

A few years ago I had come across instructions on how to repurpose an older laptop into a calendar for all in the household to use. The laptop would only run a calendar program (perhaps one or two more) where those in the house could post and update appointments or other commitments.  The original laptop screen was replaced by a touch screen while retaining a functioning keyboard.   I was certain that this had been an Instructable, but I have not found such a project on the site.  I have not found a hard copy in my file drawer or a soft copy on my backups.  Does such a project ring a bell to any of you?  If so, please let me know.
