I had a lot of Lego when I was younger (in the late 80s/90s). In a flash of nostalgia I recently remembered having a great instructions/ideas book that I loved to read through - I can't remember the number, or even if it was an official instruction manual, all I can remember is that it contained information on a 'line plotter', which used a roll of paper and a few pens to draw lines, which at the time I thought was amazing - I may have even built it.
I've been able to find out some information - it appears that the plotter was built by Larry Page (yes, of Google fame!), and I have also managed to find this picture from the book...
Does anybody else have any information on this book? A PDF would be excellent, but any information would be of interest to me.
