** NOTE: This repository contains an incomplete implementation of a CPU and a compiler and it's up to the students of FOI to do their magic and get this beast up and running. **
Secure Integrated System v. A
The incomplete CPU that was discovered on one of the computers in the faculty's basement.
This will download and install the discovered Python library
$ git clone http://github.com/foi-oss/sis-a
$ cd sis-a
$ python setup.py build
$ sudo python setup.py develop
Using advanced reverse engineering techniques we have discovered how to run the CPU:
$ sis-a -m os.mem
Where memory.sisa is the raw image of the memory containing the operating system and userspace programs. (We haven't recovered any.)
A specialised compiler for the CPU has also been recovered, although, it's implementation is incomplete, as of now it can compile only some instructions.
$ sis-ac -s fielen.sisas -o fielen.mem
It's up to you implement the missing functions and send a pull request once you're done.
The documentation files have not been recovered yet. We suspect they were on the wiped out USB stick that the agent has left behind. Send a pull request as soon as you manage to recover the files.
