These instructions have been tested on Mac and Ubuntu (donlanes). You will need some kind of a serial port to them to work.

I have created a toolchain to make assembling code for the 8051 easier on Linux and Mac operating systems. Instructions below.
<pre>
+
sudo apt-get install dosbox python-serial
+
  
mkdir ~/6.115
+
The latest version is available at https://github.com/igutekunst/6.115-Toolchain including instructions.
 
+
cd ~/6.115
+
 
+
wget http://mit.edu/~igutek/Public/6.115_toolchain.zip
+
 
+
unzip 6.115_toolchain.zip
+
 
+
echo  "export PATH=~/6.115/tools/bin:\$PATH" >> ~/.bashrc
+
 
+
</pre>
+
 
+
Test this by typing rasm test.asm
+
 
+
It should print something like this:
+

+
-rw-r--r--  1 isaac  44 Feb  9 17:55 test.obj
+
</pre>
+
 
+
Additionally, you can type
+
<pre>
+
make program
+
</pre>
+
To upload the program on the RJ31P (is that what it's called).
+
==Serial Port Settings==
+
For this to work, edit the Makefile and change the serial port to be the correct one for you machine. To find out, first type
+
<pre>
+
ls /dev/tty*
+
</pre>
+
Now plug in your serial port, and repeat the command. The item that shows up is the serial port.
+
==Modifying the Makefile for your own code ==
+
You can modify the Makefile to change which asm file it assembles by changing the SRC variable.
+
 
+
Just open the file and replace SRC := test with SRC := myfile  (without the asm). Your file must be named myfile.asm
+
==Plain Old rasm==
+
If you want, you can also just use rasm as documented in the lab
+
 
+
 
+
==prog8051==
+
If have also included a program I wrote, prog8051 which will upload an .obj file the the board if it is in monitor mode.
+
To use it, type prog8051 -o myfile.obj --serial-port /dev/thecorrectserialport
+
 
+
type
+
<pre>
+
prog8051 --help
+
</pre>
+
to see the syntax.  
+
 
+
You can edit prog8051_config.ini and change the default serial port that prog8051 uses. This way you can program simply by typing
+
<pre>
+
prog8051 -o myfile.obj
+
</pre>
+
 
+
=Mac Instructions=
+
* Copy DOSBox.app into /Applications
+
* Make a symlink  to /Applications/DOSBox.app/Contents/MacOS/DOSBox from ~/6.115/tools/bin/dosbox
+
<pre>
+
ln -s /Applications/DOSBox.app/Contents/MacOS/DOSBox ~/Dropbox/Classes/6.115/tools/bin/dosbox
+
</pre>
+
* Follow the general instructions above, but Instead install pyserial with the following command
+
<pre>
+
sudo easy_install pyserial
+
</pre>

A few notes

I have created a toolchain to make assembling code for the 8051 easier on Linux and Mac operating systems. Instructions below.

The latest version is available at https://github.com/igutekunst/6.115-Toolchain including instructions.
