> The Ophis project started on a lark back in 2001. My graduate
|
|
studies required me to learn Perl and Python, and I'd been playing
|
|
around with Commodore 64 emulators in my spare time, so I decided
|
|
to learn both languages by writing a simple cross-assembler for
|
|
the 6502 chip the C-64 used in both.
|
|
</P
|
|
><P
|
|
> The Perl version was quickly abandoned, but the Python one slowly
|
|
grew in scope and power over the years, and by 2005 was a very
|
|
powerful, flexible macro assembler that saw more use than I'd
|
|
expect. In 2007 I finally got around to implementing the last few
|
|
features I really wanted and polishing it up for general release.
|
|
</P
|
|
><P
|
|
> Part of that process has been formatting the various little
|
|
tutorials and references I'd created into a single, unified
|
|
document—the one you are now reading.

|

at the time, and one of the things I had been hoping to do with

|
the assembler was to produce working Apple II

programs. <SPAN

Garden of Eden. So, Pythons, snakes, and stories involving

really old Apples all combined to name the assembler.
