Hi,

I am retrofitting a Parallax Scribbler 2 robot to act as a turtle
robot for the Apple II. The aim is to use Logo to control the robot.

From what I can find out, the early Apple II Logo implementations used
parallel cards to talk to turtle robots. Since the Scribbler 2 already
has a serial interface I would prefer to stick to using serial. I know
that later models of these robots received RS232 interfaces but I
can't find any information on the serial protocols used. Granted my
searches have been mainly focused in the Apple II domain, I would be
happy with information on any platform.

My project : - http://lukazi.blogspot.com/2012/01/w...roduction.html

Thanks,



Alex.

I have found the solution. Redefining logo primitive commands was my
friend. This will allow me to generate my own protocol.

I'll have the results up on my blog after implementing my findings.

Cheers,
