Welcome aboard!
The wiki for the 1100 is
here.
You'll need a copy of the Rocketbook Librarian, you can get it
here.
SmartMedia cards are rare these days but
www.JR.com still lists them for sale. They are very fragile, I would not insert and remove a card unless absolutely necessary and
NEVER with the reader on. You
WILL kill the reader if you remove the card with it on. Card readers can also be hard to find but you don't need one as long as you have the USB cable for the reader. You can download the install CD from chromakinetics (link above), it should come with the USB driver. If you run Skype, it may interfere with the USB driver and will have to be shutdown before the USB driver and Librarian software.
As for actually using the 1100, I've never seen one in real life so you'll have to play with yours and share your experiences.
