Hi,

I am retrofitting the Parallax Scribbler 2 Robot to act as a turtle
robot for a Apple II computer. 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 on the Apple II domain, I would be
happy with information on any platform.

My project : - http://lukazi.blogspot.com/2012/01/waltr-introduction.html

I am trying to find out which Logo languages I can use (Apple II
preferred, DOS, Windows based) that will output turtle graphics
commands to the serial port. Having the protocol documented would be
of help but if I got the software going then I could watch the serial
stream to work it out.

This is what I am trying to get to :-

Logo Commands: FORWARD 20 -> Logo Interpreter: Assembly Language
generates binary or ASCII protocol (something like $FF $0A $00 $14 $FF
or .F020.)-> Serial card in Apple II slot -> Serial (physical cable or
wireless) -> Scribbler 2: Spin code that reads serial commands/
arguments and translates these into S2.spin object calls.


Thank-you,



Alex.

Got it sorted.

Redefining logo primitive commands was my friend.
