I loved Logo to pieces in the eighties. I had the Logo cartridge for my Atari 600XL, and I liked it so much that I bought the 64K ‘outboard’ for this machine even though I could not afford it and it make me walk in old jeans and sweaters for a year; not enough nodes to do anything useful in the standard 16K. Now a common misconception about Logo is that it only does Turtles. I spent numerous hours in 1984 to watch random walks of four turtles, but the real use out of it I got was in its capacity as an easier LISP-without-parenthesis. In fact I first understood recursion during my first endeavours with Logo. In Rexx I still use the “parse line first rest first” recursive parse technique that I learned with Logo’s First and Butfirst (LISP’s CAR and CDR). I was excited to see that LCSI still exists and even have their stuff running on the Mac. The manual from 1983 is the only thing I saved (because it smelled rather nice, and epitomized the eighties with pictures of happy people and happy turtles, in a orange and brown design that just became fashionable again). I look forward to use it again for little playthings and sometimes wish I had children to teach it to. Some things in the Mac version need to be fixed, but when they are, I’ll gladly pay for it.

I just discovered LOGO through an Atari emulator on my Mac. I started using this emulator for sentimental reasons (my first computer was an ATARI 600 XL, on wich I did some BASIC programming.
In those days I never used LOGO and now it got me re-interested in programming. I would really like to get a PDF of the manual that came with ATARI (or LCSI) logo, so I can use it with my kids, and for the sentimental reasons as stated in the blog (the typical eighties pictures and colours). Is there someone who still has this manual and would be so kind to scan it for me?

Kind regards,
