Yes. I heard about it and got curious. I liked tinkering with 
electronics back in the day and kinda wondered what this is about. It's 
just basically for my own fun. I don't expect to make something the 
world can't live without or anything like that.

Lots of info there. Well, glad it's possible. Looks like it'll take some 
doing though. Obviously there won't be anything in Debian's Repo for it 
like I hoped.

Thank you for giving me some ideas on what to look for. That'll keep me 
busy for awhile!
