Haha, I know the feeling. I used to use an IBM Model M at school in study hall all the time and used to write stories on that particular computer. Let me tell you, the kids who were trying to read or take tests loved it
I actually own that particular Model M today and took it into work for a while when I had a massive project to take care of and didn't want to use a mushy 2007-era HP keyboard. I got a lot of comments on its size, its noise, and its age. Stories of WordPerfect 5.1 and MS-DOS were shared--but my desktop picture was (and still is) a Mac Classic on that machine at work.
Anyways, I have decided to use the Plus and MacWrite II for my novel project. And yes, I will print it and send it to whoever is judging the RetroChallenge--or e-mail it after converting it to a more modern format. I would have used the Lisa, but I don't want to put excess wear and tear on the Widget hard drive since I'm trying to preserve it (especially since my system has the original box and manuals).
I'm also going to write it without any iPods. Instead, all music for inspiration will come from CDs. That's right, CDs. (I don't think most kids these days even know what CDs are, let alone records or tapes). Played on an Apple CD 300e connected to the Plus, they will be sure to stimulate my mind. Expect me to play a lot of Depeche Mode and ATB...especially since I found a CD containing "Enjoy the Silence: Quad Final Mix" at The Exchange, which I will probably buy at the end of the month when I get paid...
I have a lot of ideas for the novel and can't wait to start writing them!!!
