old laptops - I need several for grandchildren-no joke.

Long story snipped to point- My stepdaughter is beginning what will be a very nasty divorce. thus I need to keep my 2 grandkids occupied. Here's the issue. This has a near zero budget- A few bucks here ant there can be pried loose if needed. The goal besides keeping the kids occupied is to show them and all in their external lives that Linux CAN be a primary Operating System for grade school children. Any donations- offers of cheap stuff- or even practical advice will be appreciated. There is an option of payment for hardware/time helping set this up by me giving you free camping within reason.And yes- that means families too! Details further as needed. Contact me off list as needed.
