Getting a copy of Ophis

If you're reading this as part of the Ophis install, you clearly already have it. If not, as of this writing the homepage for the Ophis assembler is http://hkn.eecs.berkeley.edu/~mcmartin/ophis/. If this is out-of-date, a Web search on "Ophis 6502 assembler" (without the quotation marks) should yield its page.

Ophis is written entirely in Python and packaged using the distutils. The default installation script on Unix and Mac OS X systems should put the files where they need to go. If you are running it locally, you will need to install the Ophis package somewhere in your Python package path, and then put the ophis script somewhere in your path.

Windows users that have Python installed can use the same source distributions that the other operating systems use; ophis.bat will arrange the environment variables accordingly and invoke the main script.

If you are on Windows and do not have Python installed, a prepackaged system made with py2exe is also available. The default Windows installer will use this. In this case, all you need to do is have ophis.exe in your path.
