There's also a list-processing side to the language, cut down from 
LISP but still quite powerful.

I have a low quality, 4-up photocopy of the tutorial.  It's an
excellent piece of educational writing, with toolkits to demonstrate
computer assisted learning, etc.  Will scan it if it's not online
anywhere.

I'd be interested in an image of the ROM though.  Hopefully it fixes
the nasty SAVE bug of v1.00, but if not there's an insert in the manual
containing a workaround.

"Logo is now in the vanguard of the microcomputer revolution.  As home
computers grow in memory power and speed, Logo will grow with them,
infinitely extensible.  While BASIC Will become a forgotten curiosity,
a fossil of the early days of microcomputers." :-/
