Apple //ix

A salvaged Apple //e emulator, originally written in the mid-90's in C and x86 assembly and currently suffering from quite a bit of rot...

Project Goals

• Approach 100% emulation fidelity with Apple //e machine
• POSIX portability
• A tech playground for me :-) ... This is actually an important point... I'm doing this because it's fun and allows me to play with a wide swath of fundamental tech : virtual CPU, virtual machines, assembly language programming, video and audio programming to name a few... So you might say that the process and practice is as important as the goals.

Status Update

20131214 ...

• It builds and works for me :-) as a 32bit binary on GNU/Linux with X11 and OpenAL
• Ideally I'd like to maintain the CPU thread tightloop in assembly, and so will need to write new x86-64, ARM, (and also a generic C target) in addition to maintaining existing x86 assembly routines
• Before any significant platform/architecture porting is started, need to develop unit tests!!! :-)

Semi-Ordered TODO

• GNU/Linux x86 alpha-test binaries
• Unit tests
• POSIX x64 target (Linux, *BSD, ...)
• MacOS port
• ARM tablets (iOS, Android, ...)
• General refactoring for modularity, clarity, and portability as I go (and have tests to double-check stuff :-)
